In reply to seankenny:
Fair enough! For what it's worth I think the best bit about Tonsai and Railay is the multi pitch sport climbing. The single pitch stuff is OK (with a few really stand-out single pitch routes - Cat Wall is one place that really sticks in my mind!), but I thought there was something really special about the big routes on the Thaiwand, Ao Nang Tower, Monitor Wall etc. There are some truly amazing 5 or 6 pitch routes from 6b upwards with very little polish and in a great setting by the beach. Climbing through a huge roof 4 or 5 pitches up above the sea, on huge jugs with big exposure would appeal to many people, I'd have thought. It's a shame you didn't get to experience this!
If you do ever go back let me know and I'm fairly confident I can give you a tick list that wont leave you disappointed.
