I went to Thailand for 3 weeks at Christmas/New Year and visited a few different places, but if you only have 5 days then you'll probably only be able to do one place.
Bangkok is probably your best bet as I expect that's where you're flying to/from, and it has plenty to do for 5 days. The Lonely Planet has plenty of good suggestions of what to do, but I can give you more specific ideas if you want.
We also went to Chiang Mai in the north which is lovely. Still a city with lots to see in and around it, but it seems to have a far more chilled vibe than Bangkok.
If you fancy proper chilling then I'd recommend down south. We stayed on the Andaman coast at Khao Lak and Ko Lanta (north and south of Phuket respectively). Both had a nice relaxed atmosphere - not as manic as I'm led to believe Phuket is.
