I need some suggestions on beaches to take my kids to on St. Lucia. The kids are 12 and 15 and would prefer to snorkel and beachcomb. Preferably some place that has snacks and loungechairs available. Can anyone help me? Last year we took the "Northern Island Drive & Beach" tour through Princess excursions, although we as adults enjoyed it, I know the kids would rather be at the beach the whole time.
