Leave the FMP - not what it was, too many looking not enough partying! I prefer it on NYE - not so many people and a full on night!
If your staying at Haad Salad then you'll know the Reggae bar owned by Mr Lek - top man!!
Bottle beach is worth an overnight stay.
If you do get in the Masons keep your eye out for a real good friend of mine - older bloke with an old Saints badge (3 roses) tattooed on his forearm. He's actually retired out there (jammy git!).
Oh and as for the Ele & Castle on Samui - those chaps are a bit "large" - good blokes tho and top food. But like you say prob best to stay away on the 8th as we are going to beat 'em!
Christ I need to get back out there and soon!
