I did forget to mention we arrived on time for our ADR but still waited about 20 minutes for our table.
We also had someone steal our reservation so then we had to wait about 10 more minutes for them to go and get the people that said they were me and seat us.
I don't think that's a common problem though, lol.
The movie loop at the SciFi is 40-45 minutes. We usually overlap by about 5 minutes but that is at Lunch time. Might be longer at dinner and depends on how long you have to wait to be seated. I would think feel a bit uncomfortable with that timing as I like to be early to Fantasmic to get a good spot.
It was a little nuts. There was a ton of people waiting for walk ups and they must have gotten tired of waiting. I think the waiter was more upset than we were. He said it was the first time it had happened to him. We just laughed it off.That's crazy!
