HI Aubriee,
I thought they must have had a system like that at some point - it seemed too logical.
I suppose the only way around it would be to swipe/show your KTTW card - but that would be a hassle and time consuming.
The problem with that is that Disney tells everyone that if you have a park pass, you are entitled to ride any WDW transportation you want. There were tons of people parking at DTD, for free, and then hopping on buses to the various parks. It clogged up the bus system immensely. So, Disney stopped running those buses. It was so convenient but the 'bad apples' ruined it for everyone.
Here's the thing...the buses to and from the parks are always busiest an hour before park opening and at park closing. If you feel that you aren't going to be happy with the wait, or possibly standing, then a rental car may be your best choice. Disney transportation is truly 'public transportation'...there is no way they can run buses that arrive every 5 mins....the cost would be prohibitive!!! Can you imagine what our resort costs would be then??? Those with strollers and young children who get tired out may be better off in their own cars...they can come and go as they wish, without having to take a chance of not being able to get a seat. And before the old 'I have an infant in my arms, I deserve a seat' argument starts up...you can't discern if someone who is seated already has an issue that causes them to have to be seated and not offer you their seat. Do not make assumptions. Better to just take the bull by the horns, so to speak, and either take your chances or rent a car.
Yes, sometimes there is a longish wait for buses. The buses to DTD are the absolute worst. And yes, I have been at the bus stop at BW, waiting for the bus to MK and watched as 3 buses to AK came and went...truly frustrating. But, it's a minor irritant....it takes a relatively small amount of time out of your day. Unfortunately, when you are waiting for the bus to MK, and you have a couple of excited kids in tow, and you have just missed the bus to MK and now have to wait 15 or so mins for the next one, well...it seems like a much longer wait. One time, as I stood and waited for the bus to MK at BW, I decided to time my wait. Obviously, I need a life, but these are the things I do so that I can report back on the Transportation board. So.....I was the only one standing there, had arrived just as the MK bus was pulling off down the street (shouldn't have stopped to use the restroom I guess!!). Well, another family ambled on down about 5 mins later. The bus to MK arrived after I had been waiting for about 17 mins...as I said, I was timing it. So, the family that had come along after me had been standing there for less than 15 mins. BUT.....as they boarded the bus, in front of me, they berated the driver, telling her that they had been standing there for at least 30 mins...why did it take so %&%^%& long for the buses to get there!!! The poor driver apologized profusely, and said she had no idea why they had had to wait so long. I got up to here and told her that they had not been waiting over 30 mins, that they had been there less than 15! That driver was so relieved to hear that.
SO.....yes, it does feel like you are standing there forever. But many times the wait just seems to be longer than it is. And again...if you are going to be upset about less than perfect transportation, it may be a good idea to take matters into your own hands and rent a car.
