Welcome to the board.

As already stated, lots of places to go.
One thing to consider it to limit the number of places you go so that you do not spend too much of your time traveling and checking in & out of hotels.
You might want to consider staying at least 5 days in each location, except if it a specific short excursion, such as visiting Phi Phi island while in Phuket.
