I really like this Hotel and have been staying 3 or four times a year for many years.
You should be able to get a room for under 2,000 baht for the time you want and if you keep emailing then they will drop the tax and service and joiner.
They are in a great location and the rooms are to a high standard.
They may be pricing themselfs out of the market though and I dont think that they are value for money during the high season.
They quoted me a special rate of £1,100 for 2 weeks (thats 77,000 baht)
So I would suggest that you find a more resonable place for high season and buy your self a nice Xmas present down Bangla Road.
