Our first two nights on KPP were quiet because it was a Buddha festival. The third night Pam and I met up with a few people and had a blast! We took in a fire poi show, a reggae bar that doesn't play reggae music but it does have a boxing ring. Volunteer fighters got a free drink. One of our party gave it a try. Good for her! Then we partied on the beach. A great night with awesome people.
I learned that a regular night on Ko Phi Phi is loud, busy and fun filled. The line of beach bars in Ton Sai village provide a plethora of choice in dance music.
This means that you will hear music until very late in just about any hotel you stay in.
