This trip to Florida will be a 14 day trip and I know we will not have enough ice cubes for my daily pop drinking. We were told that you can't really use ice cube trays because the ice cubes don't really freeze. The last big trip by the time we got the ice back to the camper it had melted some and all you had left were huge chunks of ice. So what do you do for big trips and ice cubes? Thanks everyone.
