We go to a resort every summer. All meals are included, in their dining room, so no decisions about where to eat. Of course, they have a menu with many choices, but what happens is, they'll have some of the same things throughout the week--for example, prime rib might be on there Sundays and Thursdays. They offer soup, appetizers, and salad served family style (4-5 different types of salad throughout the week). You COULD pick the same entree twice in a week, and sometimes one of us does that. The younger kids, for sure--they don't have a separate kids menu, but have a few kid-like entrees--chicken fingers, hamburger, etc. My younger two could have pasta every meal, and on vacation, sometimes they do!
Breakfast and lunch are buffet, so you can mix it up as much or as little as you like. They have a salad bar, sandwich fixings, and 3-4 hot entree choices. Breakfast is similar, but with breakfast-y choices.
