Day 13-15 >>Bangkok >> depart.
It can be helpful to regroup after the flight to Bangkok. As an alternative you could fly directly down to Phuket if you are tight on time. Then stay the other end in Bangkok. Flights can be the best way to see the most given a shorter stay and as you are already at the airport is there a departing flight? This will suit very few people as Thailand is a long way for most so we recommend to stay a couple of nights in the capital. It's great easy and you can get a great hotel for not too much money though Thailand isn't as budget friendly anymore.
Other islands to consider:
Koh Lanta - A more relaxed scene as its development is controlled. Some of the longest beaches in Thailand beckon and this is an escape from the overcrowded.
Koh Lipe- Listen to some Dua Lipa while in Lipe :) A small island which in many ways is similar to Koh Phi Phi without the dramatic cliff scenery but also not as intense or annoying.
