Our family of 4 had been planning a trip to Puerto Rico, but with the swine flu outbreak, we're rethinking being cooped up in an airplane with lots of germy travelers. We'd been planning to splurge on the Las Casitas Resort in Puerto Rico and are now looking for a domestic alternative--so something on the water of some kind. Onsite babysitting is a must, as we have two toddlers and want to have a few date nights on the trip. I'm also in dire need of a massage. Recommendations?
