In the spring, definitely the dessert. In winter the south, else before kids are out of school(before memorial day) and after the are back in School ( after labor day). Spring training in Arizona is fun.
I Loved seeing the Grand Canyon, Cancun, Cayman Islands, Puerto Vallarta, Mexico and Santa Barbara, Ca. is the most beautiful city. You just have to know where to go very historical in its buildings, churches, & its city. Those were just to name a few.
