It's so much easier to have a great time when you know your kids are well taken care of and having a great time of their own. So take off on a mountain bike or water-skis. Fly on a trapeze or hike a mountain. Team up for volleyball or softball. Work out in exercise classes or on the tennis courts. Try yoga or massage classes. Or just relax while you soak up the warmth of the sun and the friendliness of the people.
