Hi there....we will be checking in early Sunday AM (flying in Sat. evening staying at POP one night) and will be making a grocery run (juice, water, milk, snacks, etc) before heading to Beach Club Sunday AM. Chances are that the room won't be ready...so besides holding our luggage...will they hold groceries? Especially those that need to be in a fridge? How does that work? Any special tips to make sure you food doesn't disappear? Thanks!
