Period question? any help is appreciated! :D?

Okay, so I asked a question a little while ago about starting my period and my waverings about using a tampon while on vacation, but I just started my period! So I won't have to worry about it! My question is, will the worst of my period be over by the time I get to Florida? We leave on June the seventeenth, and I started my period today, June the fourteenth. We were planning to go to a waterpark on the eighteenth, and I was wondering if the worst would be over by then? My periods usually last up to five days with the last two days being just a little bit of blood. I hope everything will be okay, because I don't want my period to ruin my trip! Can you guys give me any answers? Thank you so much!
