Seeing as though this particular forum is so quiet, I thought I would tell you about my February 2011 travel plans.
Ok, well we have been to Thailand no fewer than 7 times in the last 10 yrs but we never actually made it over to Samui as we decided to leave that for our honeymoon

We will be flying direct from Perth to Phuket with Thai.
2.5 hr wait (enough time to clear immigration and collect baggage and proceed through customs) - and then re check our baggage for our onward flight to Samui with Bangkok airways.
Staying 5 nights at Centara Grand Beach Resort Samui.
Have read some good things and some not so good things so I will be sure to report back on our experience there.
Then moving on to Koh Phangan, staying at Milky Bay Resort in a beach front studio for a couple of nights before heading back to Samui for 1 more night so as not to panic about making our mid morning flight the next day.
Then on our return to Perth, we will stop for 3 nights in Bangkok (enough time to see my favourite tailor and for the mrs to fill her case and probably mine too, with dresses and other bit of cloth)
Staying at Centara Grand at Central World.
We have not planned any activities, we will take things as they come.
So many good eating choices on the island that there is no way we'll get to try all of them but we'll be sure to give it a good go.
Anyhow, can't wait.
