We're a young minded couple in our early 50s and going to Koh Samui and Koh Tao in June and are wondering which resorts to stay in. We like some nightlife and particularly enjoy a live band but don't really want to be surrounded by partying travellers. We're going to Koh Tao for snorkelling so the clarity of the sea is more important than the nightlife, though we don't want to be in the middle of nowhere! Koh Samui we've narrowed down to Chaweng, Lamai or Bophut - any suggestions as to which would suit us best? And are the taxi charges as bad as I've been reading? For example, if we choose to stay in Bophut, how much should we expect to pay for a taxi to Chaweng?
