HI, Thailand has long been on my bucket list and I love to plan trips but this keeps getting put on the back burner . I need some help! We are a couple 47 and 60 yr old. WE like culture, food and want to see temples and elephants and snorkel beautiful beaches. We will have a max 22 days to travel included travel days. I cant figure out the order in which it would make sense to travel, how long to stay where, and which islands to see... In my mind I am thinking Bangkok 2-3 days just to see the Grand Palace and Reclining Buddah) (NOt a fan of huge busy cities) , Chang Mai 3-4 days then maybe Krabi 2 days( b/c it seems like a good jumping off place of island hopping, ferries??) , Koh Phi pHi 2-3 days, Koh Lanta 2-3 days. Then I would like to fly to see Siem Reap in Cambodia a couple days. We will fly out of San Francisco most likely. Any tips appreciated. Thanks!
