We waited for one hour and 10 minutes after our PS time on November 10th, which was 7:50 pm. But Wishes was at 7:00 that night, so I don't know why we had to wait so long.
Part of the reason was that we were a large group of 12, but when making our PS, we were told we would have to split up into 3 tables of 4, which we said was fine. However, they didn't even have one table of any size available when we arrived. This had nothing to do with the fireworks, since they had already taken place at 7 pm and we didn't get a seat until 9 pm, while our PS was for 7:50 pm.
Despite all this, our meal at CG was the best we had, not only for the great view but the food was delicious. Our kids enjoyed doodling on the paper tablecloths - they provided the crayons, so it was very kid friendly for us.
I would definitely go back, but the wait was a bit much and without justification. Maybe everything is so good that patrons just don't want to leave.
