Well Meg my old buddy. Ill let you into a lil secret. I had something similar to this last year. I entered into a competition in a magazine and won a £2000 holiday voucher and an awesome Canon camera. My gf (at the time) and I felt like we won the lottery. We walked into all the holiday shops and got stacks of brochures ranging from cruises to skiing to beaching.
In the end we decided either drive route 66 for a month or spent christmas and new years in 5* hotels in Thailand. Due to spending money we went with the Thailand one. We sold the Camera for £1100 and that paid for the additional £700 of stuff we wanted to do and gave us a head start on the spending money.
We decided to stay 4 days in a 5* hotel in bangkok where we saw lots of culture and some wierd things, 3 days in a 4* in Chang Mai, where we went to an elephant sanctury and a tiger breeding place where i got to hug a tiger and play with it. (NEVER touch its face)
Then we flew to phuket for 8 days and stayed at a lovely hotel in the most expensive room (the same hotel Leo DI C stayed at when filming The Beach).
Came back all relaxed and full of photos, and got dumped. Nice......
