I discovered the power of hot water in Florida last year. After walking all over Epcot all day, often with a limp because of leg soreness, I was the last person to use a hot tub at a resort nearby (not at Disney World). When I got out, I could feel a difference right away. That did not completely relax my leg muscles like a massage would, however, so I decided to get one massage on a cruise in addition to dips in hot tubs every day. That is all the relaxing I will do on a cruise outside my cabin.
