This is the best hotel pool in Hawaii and among the best in the world. It's almost a water park. Kids force their parents to spend exorbitant sums to stay at this hotel primarily to have easy access to the pool. It's huge. It's got tunnels and slides. You can buy drinks in it. Here's a video tour that hints at the hypnotic allure of the Grand Wailea Resort and Spa on Maui, the ultimate Hawaii hotel pool splurge. You may never visit the beach at Wailea but you'll definitely get wet. What do you think? Is it worth $600 per night?
