Thailand is flooded with massage parlours each offering almost the same price packages. Found one here is Sadao which offers 300BHT for a 2 hours massage. A bit pricey in my own opinion as the ones in Hat Yai are only charging 240BHT for the same 2 hours. Nevertheless, it really is a good 2 hours of relaxing session.
The package offered by Mei Spa is very competitive. You are allow to acess all the facilities for unlimited hours, plus one 45 minutes massage - either oil or ancient massage.
Spa facilities including pool, steam room, sauna room, buffet (eat all you can) and mini cinema.
A pub for you to relax, sit down enjoying the food as well as soft music. The owner as well as the staff are very friendly - really 'made yourself at home' atmosphere.
