spent about 3 days Bangkok and then off to Kho Phi Phi. Three days is really all you need in Bangkok as it get's to be a big "been there done that" scenario (but that's my experience). We flew from Bangkok to Krabi and then off to Kho Phi Phi. This was about 2 months before the Tsunami and I would go back in an instant, I found it very relaxing with great snorkeling and some beautiful beaches. We did a nature Hike as well and that was pretty cool but hot as hell.
A little story I wrote, you'll have to excuse the writing, I was trying to sound smart and edumacated
