Travelocity has it as well. There also is a $16 room available. They use the Baht rate as USD rate. THB1915.00 = $51.08. Based on my experience with Travelocity (MO Tokyo mistake), the correct (USD) rate will be transmitted to the hotel. Fighting with Travelocity is not fun, so book with Priceline.
I am in BKK -- we shall see. Thanks, OP!
