My period just started and i have a family celebration into 3 days that involves water, what do i do?

Well in 3 days (by then my period will still be on because my periods usually last from 5-6 days) we are heading for Destin to rent a condo and go to the Big Kahuna Water park, the beach, and shopping. As you can see the majority of my 2 days there is spent in water. What should i do. I've heard that tampons are safe to wear, but i don't use tampons. I do not want to miss out because my family doesn't get along to well so this is a VERY rare occasion. Are there any other possible solutions?
