Hm. That would certainly make a lot of people angry. It’s one thing to have a fcfs system- but it’s really different to have a system that encourages people- and in some cases, requires them- to get up early and make reservations 180 days in advance-even planning park days based on which reservations they could get.
I’ve been in many of the restaurants, and I can’t think of many of them that have adequate waiting space for guests. Many of them have very small areas for guest waiting. “There is a 45 minute wait. We will text you when your table is ready. Go wander around the park in the sun (or the rain) until we text you.”
It doesn’t sound like fun to me to wander around a theme park looking for a place to eat, not knowing whether there will be an hour wait after I’ve walked all the way across the park to get there- especially when I know that, six months ago, I made a reservation for me and my family to eat there and made it fit perfectly between my scheduled fastpasses.
I hope that is not what happens.
