I've said this on another forum, but everyone who is in favor of these return tickets is just SO SURE that they will never be the ones denied entrance. I keep seeing people say that this will give them a chance to eat at BoG when they never could before. No, you always could if you chose to wait in line, but by eliminating the line, now even MORE people are wanting to try it out. But guess what, capacity hasn't changed. And the moment word gets out to the public that the only way to see an attraction or eat at a certain restaurant is to get a return ticket, those tickets will be gone with minutes of the park opening (think TSMM or Soarin' legacy FP, only worse since this is Literally your only option to do the experience. No "eh, well just do standby," option anymore.) The longer one has to wait for something, the fewer people want to do it, which means eventually the line will stop growing as you reach that "too long" threshold. Take away the physical line, now there's nothing dissuading people from joining the virtual queue (aside from time conflicts, perhaps). All they're doing is INCREASING demand.
Early on in this thread, someone even said that they'll be sure to get the pass even if it's for two or three hours later. Then when their time rolls around, they'll decide whether or not they want to actually eat there or not. Great. Now they just took the spot of someone who really WANTED to eat there (Who gladly would have waited 30 to 40 minutes in line originally) but arrived at 9:15 when all the passes were distributed.
