Not a luxury hotel per se, but we have negotiated a fantastic rate at the Barai in Hua Hin (part of the Hyatt but almost a separate hotel), as part of an event in February next year.

Full details of event are here.

Rates are inclusive of service and tax and valid for 12th-15th February (possibly also shoulder nights on request):
Barai Balcony 17,500 THB
Barai Pool 20,000 THB

Benefits of the Barai (over 18s only):
- butler service in suite
- use of club lounge and club pool
- breakfast, drinks and evening cocktails and snacks in MacFarlane House (more exclusive and higher quality than club lounge) or breakfast in all-day dining room
- daily steam room and milk bath prepared by butler in-room
- use of tranquility pool
- private beachfront day beds prepared by butler
- 2 laundry items per day
- minibar
- daily 1h massage for 2 people

Benefits of event
- cocktail reception on first day
- BBQ dinner on the last day
- 1400 THB per person per day activity allowance (activities TBC eg cooking lesson, water sports, garland making etc)

I appreciate that rooms and dates are limited, but the daily rate for this time of year is 28836 THB (pool suite) and this doesn't include the 1400 THB daily allowance, BBQ dinner or cocktail reception, thus the negotiated rate is almost 40% off.

Club rooms and suites are also available at a great rate, but don't really qualify as luxury hotel.
