That is a really good point. I see a lot of complaints about difficulty getting FP+, staying up till midnight, etc. I forgot about this group. Now I can see how those types of people too don't love this system. If you have a life before your vacation, you are working hard and sticking to a schedule all the time; and this should be your time off. I agree!!!
I am not thrilled about having a schedule to keep either. I plan to try to wake my family up early two days on vacation!

Not sure they'll love that! I hope they will want to, so that they can enjoy the things I have planned. But where I need to stop myself (and I promise that I will!!!) is... so what if they don't want to wake up? Really? So what? I miss the Welcome Show? Ok, bummer. I might even miss the first 5 rope drop rides I'm hoping to try. Well, rats. But, by say 10:30, we will still be walking into the Magic Kingdom as a family, for the first time. How cool.
What if my son wants to meet Talking Mickey at 11 am, with a 30 minute wait, and ruin my Peter Pan FP+? Well, gee, why not meet Mickey? So, I don't really see how I ABSOLUTELY HAVE to keep to a schedule. I'll do the best I can. I'd rather not miss an ADR due to the no-show penalty, but once a day I'm sure we can all plan to get one place on time. Roll with the rest. It's not like you have a shock collar on to zap you if you miss your 7DMT time!!!
Another thing I remember reading, and I'm sure it was here on the DIS... a family went to Cedar Point or some other coaster park like that, and it made them really appreciate Disney (number of rides they could get on, cost of food, friendliness of staff). Last summer we went to Cedar Point for the day. I think they have something you can buy to bipass lines or make them shorter or something; we didn't get that as it was a free work trip. So, we waited in the sun for a few rides. Lines were long, rides were short. My husband wanted a thrill ride, so he went without me and DS, so the family was split. I didn't know where things were and walked around alot. We ended up at the kiddie bumper cars for maybe two hours. My point is, if I had planned, and had either paid or had access to their pass system, I probably would have had more fun, but I might have had a "plan" or schedule for my day that I had to stick too. So you play it by ear at any park, and you will wait and miss things, but you'll do so at your own discretion. If you plan ahead at any park, you'll get to the items on your list, but you are bound by some schedule. So just pick which you want to do and go with it; no right or wrong way. But my point is I think that you will need to plan, and then adhere to the plan; or fly by the seat of your pants and miss or wait for things, no matter where you go. Just a thought!
