My family of 6 each took our own carryon, what I didn't know was that where we stayed provided laundry service every other day, we actually could have packed lighter and that was each of us bringing our own snorkeling gear. We are coming again on March 27th and I feel your excitement!!
Cant advise enuf though to buy a baby oil/ skin so soft oil to repel sand fleas, they do not seem to be deterred by ordinary bug spray.
