Help with itinerary:

First time to Phuket in March for 12 days! Does this sound reasonable? Interested in beach, snorkeling, trying restaurants.

1 day flight NYC to Bangkok 

3 days Patong  

1 day Phuket Old Town

2 days Phi Phi 

4 days Kata (also want to do a Phang Nga Bay day trip— should we throw it in here?)

1 day Bangkok, flight back to NYC 

Any advice or recommendations? Thank you!
