The buses have two tie down points on them, but some drivers will allow a folding wheelchair to be folded and held if there is space. There are a couple of special buses that have (I think) 6 wheelchair tie downs, but these are request only, and are intended for parties travelling with a lot of wheelchairs (e.g. school groups, clubs etc).
Correct.
The buses have 2 tiedown spots, plus a number of folded wheelchairs can be brought on (similar to their being no limit to the number of folded strollers being brought on as long as there is room).
This is untrue the buses follow the 5+rule as well.

A 'party' is defined in the WDW Guidebook for Guests with Disabilities as 5 plus the person with a disability.
For attractions, that is usually strictly followed (at least in my experience and in the experience of many other people who have been to WDW a lot of times).
For the buses, some drivers follow it and some are more lenient. The large parties that were allowed to board together are the exception rather than the rule, but they are the ones people notice most and comment about.
In many cases, the whole group would have been able to get on the bus anyway and would have actually even gotten seats if some had stayed with the person in the wheelchair/ECV and others had gotten into the line to board the bus. I would think the reason some of the larger parties do stay together is fear of not being able to get onto the same bus and rather than get in the line and worry about it, they all get in with the person traveling with a wheelchair or ECV.
BroganMc, if you reread my post you will fine nothing offensive about ECV users or even their 5+ family members loading with them. The problem I saw in May was that literally 15 other people would board with that young lady and toward the end of the week, she herself said she no longer needed the ECV and did not want it. It was her family that kept insisting she use it, just so they could be guaranteed seats on the bus and easier access to some rides. You may have had to be there, but this young lady was totally fed up and she herself said she did not need or want the ECV and was refusing to ride it in the parks, insisting that someone else ride it. They were arguing quite loudly about it, in fact. Everyone on the bus heard them..................................
If I offended you, I apologize. I am the one who will usually take up for people on an ECV. If someone waiting in line ever moans about one, I will let them know right quick that they'd better be grateful for not having to use one. My mom would give anything if she didn't. I let them know how people have a tendency to ignore the ECV rider and how people just walk out in front of them and then act like it's the ECV rider's fault. I also let them know that we should count our blessings everyday that we have two healthy legs and the good health to stand and walk anywhere we want to. Sorry, but I too have no patience for people who complain about ECVs, however, I also have no patience for a family like I saw last May who were definitely laughing about taking advantage either.
I would not take it personally, as BroganMc said she was using a quote of your post to 'reply' to a lot of recent posts where people were complaining about large groups getting on the bus with one person with an ECV. Your post was well thought out and reported a much more complete picture of a situation.
There was a 'flurry' of threads/posts about the same subject in the past few months. My guess is that a lot of people were reporting the same situation/party that you saw because the situations reported were so similar.
If that family all got on twice a day for a number of days, a lot of people saw and heard them. Instead of one family being posted about once, there are many posts about the same family, with everyone thinking they are 'reporting' a different family. So, one family getting on with 15 people becomes many people doing the same thing.
That flurry of threads/posts/irate complaints is what I think BroganMc was responding to, not your post in particular.
I think that the people in your situation had nothing to 'lose' by behaving the way they did. They 'saw' a real temporary need as an advantage and 'used' it for whatever they could 'get'. Because of it being a temporary situation, they didn't see the many 'downsides' of having a disability and only looked at the 'advantages'.
I think people in a temporary situation have little 'incentive' to behave in a more responsible way because it was only a temporary situation. Next time they come, chances are good that no one will need and ECV.
Most (but not all) people with more permanent situations are aware of how their behavior may appear to others and try to not do anything that reflects badly on people using whatever assistive device they use. Most have been on the receiving end of other guest's bad opinions/stereotypes about people with disabilities. (This is not to say that all guests with permanent disabilities are paragons of virtue - some would be impatient and rude without a disability and continue to be that
with a disability.)
Some people with temporary disabilities are
very aware of how they might appear and don't want to be perceived as 'taking advantage' of anything (even to the point of causing themselves pain to avoid other people seeing them ride in the queue and wait the same amount of time as everyone else).
The people who don't care how they appear
do affect the treatment that all the rest of us get.
BroganMc, you said something else in your post that touched me. You said that anytime people went with you that they knew they'd have to go slower and it was a drag. Did you stop to think that maybe those people just wanted to be with you and couldn't care less about your pace. Due to financial reasons and the fact that my parents never took us on vacation, I didn't get to go to WDW until I was in my 40's. About a year later, we had to put my dad in a nursing home and my mom had to move in with me. I was determined to take her on her first trip to WDW. She wanted to go, but knew she couldn't walk that much. I had to convince her she wouldn't be a burden if we rented her an ECV. She kept saying she didn't want to slow me down. I don't know how many arguments we had over that subject. I had to almost force her on that plane, with her being so excited, but at the same time afraid of 'slowing me down'. I wanted the trip to be magical for her, so we went in early Dec for all the Christmas stuff and I had purposely booked ALOT of character meals, an Illumination Cruise, Hoop de Doo etc. Yeah, we took the trip slower than I normally would, but we had soooo much fun. Seeing the look on that 72 y/o face the first time the characters gave her a hug and a kiss was priceless. No way was that ECV a burden and no way was my mom a drag!! Those memories and pictures are priceless to me, just as I'm sure your friends and family's time with you is priceless. It doesn't hurt us to slow down and just enjoy the moment. My mom's going back to WDW with us in September (for her fourth trip) and there's nothing I wouldn't do to make her trip special. That ECV is going to help. Her choices are: she uses the ECV or she can't go. I dare anyone else to make a snide remark about her being in it. No way is hanging out with her going to be a "drag". I'm taking my momma to WDW. We're going to ride Dumbo, we're eating with the characters, we're going to
MNSSHP, my mom is going to get to see Cirque de Soleil for the very first time, and we're going to make some priceless memories. That ECV is going to allow us to do it, just like yours allowed your family and friends to make fantastic memories with you.
There are some very good points here.
My FIL would not rent an ECV for many years, even though he could hardly walk and would be in pain all evening with ice on his knees. It hurt to watch him have to rock to get out of a chair and toddle around on knees and hips that we knew hurt with every move.
It also hurt to see him miss out on things we were doing and miss out on being able to see his grandchildren enjoy the parks. I don't know if it was pride or shame or what, but he was well aware of people with wheelchairs since my youngest DD can't walk at all. He was also aware of the negative comments we sometimes encountered and saw himself as 'not disabled', and so, worthy of those comments. He was aware that his inability to walk or stand was a 'slowing' factor for the rest of us. He didn't understand that we wanted him with us, slow or not. We just didn't want to cause him any extra pain.
When he finally got an ECV for the first time at Epcot, he was a different person. He didn't just station himself in one place while the rest of us went on things. He said it was the first time in 10 years that he actually ended the day not in severe pain. We had a couple of years of good trips where he rented an ECV and we could see his excitement at seeing things he had not been able to see for years.
I would agree that most of the people using a wheelchair or ECV probably look at themselves much differently than the rest of their party looks at them. Where some people see the wheelchair/ECV as a negative thing, I see it as a tool to assist with a limitation (like glasses for the feet).
