On MMs, we eat a quick/small bite at the hotel and do as many rides as possible in the first hour. Then, we stop for a real/filling breakfast at the River Belle Terrace and enjoy the views of NOS/ROA/Haunted Mansion in the beautiful clean morning light. It's one of my favorite DL activities! Another option is to do the MM hour on rides, then go over to the Carnation Cafe for breakfast and see Oscar (weekdays only).
This breaks up the routine so we don't have lunch everyday in the parks. DL breakfasts hold us over to dinner, with a small snack in-between.
