Because we want to bring back frozen fish from our fishing trips to Cabo and Mazatlan we always take our cooler on wheels. So we pack it with things we will eat while there. For example: cereal, crackers, 6 pack of bottled water(to get started) microwave popcorn, can of spaghetti sauce,spaghetti,peanuts,freezer ziplock bags(some 2 gal.for fish),coffee,filters,dry creamer,sugar,peanut butter,small fruit cups, etc. You get the idea. I know some of it you can buy easily and just as cheap but as long as we have the cooler we just as well pack some of the snack stuff we will use then we do not have to get as much at the store. When we get to our resort we get more water in gallons and refill our small bottles to take with us to the pool etc.
If I leave enough room we can put our lightweight jackets from cold weather in when we get to the airport. We take a shuttle from our hotel or park and fly so get by with a med.wt. jacket. If we do not take the cooler I just take coffee,filters and creamer. If we do not get fish we can always put other stuff in in coming home.
