To be honest, all the arguments about what is the “fairest” method of distributing ROTR’s limited supply boil down to “if it suits my touring style and I got a boarding group, it’s fair” and “if it doesn’t suit my touring style or I didn’t get a boarding group, it’s not fair”.
There is no way on god’s green earth that
Disneyland could come up with a boarding system that makes 100% of park goers happy. If they did FP with a standby line, the fast passes would also be gone in less than one minute after opening, and then everyone else would complain that they spent $84 for a day ticket to stand in line, and the ride broke down, and they didn’t get on anyway. Or if they did, they spent $84 to stand in line and ride one ride. BUT people who have the chance to go back a lot, don’t mind wasting a day in line, and want to sleep in might be happy.
I personally don’t think Disney will change the boarding group system for a long time, and not unless it either becomes unnecessary because interest has waned OR because a critical mass of guests are truly unhappy. Right now, it seems like this system works for almost everyone, with only a minority finding it unsuitable.
