I might be a bit late to offer any advice, but if you are going to Ko Samui, i would recommend to hire a jeep and drive the whole island for a day or two. Go to the Chedi spa not far from Poppies resort and you can have an outdoor massage that's out of this world, alongside your girlfriend.

Ko Samui is one of my favourite places in Thailand, you'll love it. Chaweng is very tacky now, but their are far better places to discover on Ko Samui!

It depends how far you want to travel and how much you want to rough it. You could visit Malaysia up to Thailand by train and stay in pretty good places for the money you have. Singapore is a must, but not for too long. Bangkok is also a definite, but stay somewhere decent on Sukhumvit. And if you were going to the islands, i would miss Ko Pan Yang (the beach parties) it's crowded and everyone's wasted (unless you like that sort of thing) but go to Langkawi in Malaysia (really lovely people, magical place and pretty cheap) and Ko Samui (to experience and get a great massage at the Chedi), or Phi Phi which was beautiful when i visited before the tsunami, but now apparently has been taken over by pirates???

Or, if you want to go really far - The Cook islands are great to travel, and one of the most beautiful places on earth. You can visit Raratonga, Aitutaki...realatively cheaply and stay with locals or at a resort.

I could mention loads of great places.....better not confuse you too much!

Personally i would go with the good weather...
