Hi Sue,
Good to hear you had a great time, we were in Krabi in November and stayed at the Somkiet Buri and loved it. We will also be back but we thought we may stay at the Golden Sands Resort on the beachfront, did you see it? When you get to the beach where you pay for the longtails and turn left, it was one of 2 resorts along the foreshore. Did you see all the beach massage places just past there on the way to the Last Fishermans Bar? It was a fun place to spend the day.
I have a few questions about Khao Lak. Is the main town area reasonably built up with plenty of shopping and eating options as there are at Ao Nang? Is there a really nice beach within walking distance from the town? I presume the beach would be nicer than AO Nang, but is it as good as Phra Nang or Railay beach?
Hopefully you get over the post Thailand blues soon, I have been back for 3 months and I am still struggling. I need to start planning my next trip or I will go insane.
