So I’m thinking of traveling in September to see as much as i can of Thailand in about 2 weeks as I’m visiting the north,middle and south. I’m not trying to really get to know each city but just get a general view of each one here goes the itinerary

Arrive in Bangkok stay for 3 nights

Fly to chang rai stay for a night or 2

Bus to chang mai stay for 2-3 nights

Fly to Phuket and go to Khao sok stay there for a night

By bus and ferry head to Samui and tao and stay there for 2-3 nights

Then head to Krabi and island hop back to Phuket for the rest of the duration and fly back from Phuket’s airport

Also concerned that I’m traveling in wet season Should i keep anything in mind? I also plan on carrying checked luggage with me and traveling with a group of 4 General advice is very much appreciated Thanks in advance
