I love planning ADRs, but I feel like that is different, *simply because it's easy to come and go for meals. (At least for me.)
However, if all of you want spontaneity, and don't want to plan ahead... then *don't* *
I'm not trying to sound rude, but I've been (with. several different people) to WDW like....4 separate times since FEBRUARY of this year, and no matter how much in advance I have booked the trip, I didn't get one FP+ ahead of time. If I got there and crowds were bad, I would just go in to the app and organize it for myself and others later in the day, and I never once had a problem with getting all the FPs that I wanted...but even in those cases, I grabbed them just in case, and didn't let them control any of us. Most of the time, when our window rolled around, *we'd already been on the ride. So it was just extra during what might be a busy time for the ride!
If you think that isn't 'spontaneous' because something was still planned...then you should probably rethink what it's like to actually be at Disney; *half way through the day, *you definitely know what the rest of your day is going to be like as far as what you'll do for meals, and where you'll be in the parks. There's a difference between spontaneity and aimless-ness. *
The only exceptions there are at the moment are 7DMT and Frozen Meet and Greet. (Excluding ADRs, because I really just don't think they are a problem. Restaurants are just that, *especially nice ones. I for one am glad they dont shove people in and out like they do on rides.) If you want to be spontaneous and get in a 3 hour line, I won't stop you. But you have to be reasonable and know that these are brand new rides, in parks that see upwards of 40,000 people on any given day, who also wanted to do that exact thing on their vacation. If you want to do that, *but not wait in line, I think it's fair to expect you to book that experience far in advance. There's going to be a day when you won't have to, but if you want it NOW then I don't think that's too much to ask, because apparently it is that important to you.
Anyway, *rant over. It's sad to see all of you bummed out over this new system. But I feel more spontaneous than ever now that I'm not with a group of people that checks the clock constantly so they know when they have to run across the park to go print out FP- To each their own, I suppose.
