While I agree that the CMs will almost always warn you that the wait will be 45 minutes for a waterside table (and it is general much less than that), there is one time when that is close to true. They seat the first round of guests at the tables along the water. So later round of guests will have to wait until one of the first tables sat finishes. So, if you have a 11:30 reservation, you should be okay for a waterside table (we've been able to request one), but if you have a noon(ish) reservation, you'll have to wait until the guests seated at 11:30 am to finish before a waterside table opens up. So if you want lunch, I would make sure to get a reservation for opening.
