Worried about getting cycle during a trip!

Okay so U have this wealthy friend who taking me to the Bahmas for thanksgiving breaking, and we return on Saturday and I am suppose to get it my period on Monday I am worried that I might get discharge or somthing whol swimming or stain her sheets! Should I wear panty liners to bed and bring pads and tanpons (even tho I have only worn a tampon twice and can't figure out what hole it is?) just in case... Or am I worrying to much?
