As for waiting for an hour to get waterside seating, that is the choice I have always had to get that particular table type. Request table side seating is just that, a request. They will not guarantee you get a table by the water even when you make that request on your priority seating. And priority seating simply guarantees that you get "priority". Its not a guaranteed time to be seated with or without special requests. They usually make that pretty clear on the recorded message you listen to before the cm comes on at the
Disneyland dining number. There are limited tables by the water and everybody wants them. So the odds are not all that good especially the later times. By the time 1:20 runs around the restaurant has been open for almost two hours and at that point its basically luck and extreme amounts of patience that will earn you a waterside table. You make a reservation to get the next available table at thte time on your priority seating only.
