You can show up early for your reservation and tell them you are willing to wait to get the table you want, but they won't take a request ahead of that. We sat to the left of the fire pit, almost at the windows, but it was sooo crowded we decided not to wait for the tables right by the window. If you are going to see Wishes, make sure you get there at least 1 hour to 1 1/2 hours before Wishes is scheduled because if people know it's coming, they hang around when they are done eating.
