Cambodia or Phuket?

As of this Monday we have 18 days in Thailand, none of which we have planned. Its the only leg of our trip which we haven’t booked anything for, don’t worry it was intentional.

The plan was to go from Phuket ot Ko Samui and then to Bangkok where we fly to Calcutta, India.

We were wondering whether we should say Phuket to Phuket and go to Cambodia instead after Ko Samui…

Help us decide!
