We generally do breakfast in the room- good coffee, dh likes bob evans breakfast burritos- I like bagelfuls- some fruit and cheese. (Or leftover dessert from dinner the night before
). Sometimes donuts.
You can pack lunch into the park in a soft sided cooler. ALWAYS bring water!
I have not done this but have thought of it often for dinner. If you are driving, bring a crockpot. There are about a million things you can make in it with no effort. Imagine coming back to the hotel to dinner ready to go.
