I have decided to take my first solo vacation for my 40th birthday. I want to do a resort/spa vacation to celebrate myself. Most of my friends have children, spouses, mates, and, frankly, if I wait on any of them to go anywhere or do anything I wouldn't ever leave the state!

Anyway, I've decided that I want to do something beach-like but relaxing, leaving on Sept 1 and returning Sept 6. I need the trip to be budget -friendly (whatever that is), since I have just started a new job, but I want to enjoy my experience. I'm not looking to do anything crazy--no crazy diets, exercise, or anything too far off the beaten path, but just a quiet, relaxing vacation that might have some enjoyable off-site excursions. Since I don't have children, I would prefer to go somewhere where there will not be a lot of interaction with kids/families----again, stressing a quiet, peaceful getaway. Lots of massages and beauty treatments would be fun to try. Can anyone recommend a resort or even a location? I live in the Midwest, so I don't want to go so far that I am so jet-lagged that I won't enjoy myself, but I am open to going as far as is feasible.
