Some days you just don’t want to get out of the pool for cocktail hour. If you’re at a resort with a swim-up bar, great. However, until you get that installed, maybe settle for a drink preserver ($11). That’s right, it’s like a little life preserver, but for a red cup, because drinking is statistically more fun when you’re floating on the water. It seems like a Malibu cocktail would go well with the pool.
