Going on a 4 day seminar out of town, what types of non refrigerable or small refrigerable items?!

cream cheese and bagels. Only the cream cheese needs refrigeration.
Peanut butter
small cans of tuna salad that do not need refrigeration at all and once open, are only enough for a single sandwich.
all kinds of fruits need no refrigeration
granola bars
If your room will have a kitchenette area, those individual cans of soup work well too that can be heated in a microwave in the container they come in. Campbells Soup at Hand I think they are called.

Hope you get a room with a kitchenette
They have those little microwave meal like roast, chicken dressing, chicken dumplings, not to expensive and very tasty!! They have them at the dollar store as well as grocery store. They are non refrigerator items. Lots of choices.
Here are some:
