2) Joining groups, and saying who can reserve for whom is still a pain. It probably works GREAT for 98% of people, but we got screwed on three different trips.
3) The way they track photos is great for small parties, but it's a pain for groups that get together, split up, get together, split up, form with another group of people for a few days, split up, etc.
4) Doesn't work on the cruise ships yet. It'll be great when it does.
5) You can book three rides. When you're done with the third one, you can book another one. When you're done with that, you can book another, etc. They don't make this well-known, so we ended up with just 3 rides per day. Could have done more.
6) My wife and I have different reasons to be in the parks, at different times of the year. But we can't have a POOL of park tickets. Nope, you have to pre-allocate the tickets to each band. That sucks. Either that, or let me move tickets between our bands however we want.
