We have decided on advice from tripadvisor forum input (thanks so much!) to go to Koh Tao insteadof Koh Lipe in May. Wondering now what advice anyone has about 1) Dive shops that at reputable and 2) where to stay. We are in our forties but not stuffy but not party all night girls either. Ideally, we would like somewhere a little more quiet with a nice beach. We are hoping to spend about less than 3000 Baht / night. Any advice would be most helpful:) Thanks!
