Plan on at least an hour if not more. Breakfast is usually a bit shorter but we have spent 75 minutes easy there after check in. There's a line for pics once you get in (and they can be slow in the morning when everyone tries to get in for 8 am even through their reservation is 8:50 (haha), then the line for your table, then the princesses come out, make rounds, your food, and then the wishing ceremony.
