My husband and I are heading to Thailand at the end of January - our first time there. We are in our early 30s. We'd like mixture of culture and easygoing, secnic beach-hopping for our 12-day trip. What we don't want is to travel all the way from Chicago and feel like we didn't get real Thai flavor. That said, we're not at all averse to places with a tourist infrastructure; we work hard and would like to be able to relax without too much difficulty in the process.
I'm thinking about three to four days in Bangkok, perhaps with a day trip thrown in, followed by three or four days based in Ao Nang (side trips to Phi Phi and Railay) and then three or so days in Ko Lanta. Does that seem reasonable for a first trip? Any other suggestions? Am I missing something?
