I have stayed in a temple.
You better find one that has hotel facilities.
Golden Buddha Pattaya, I had to get up 03:00 to put out prayer books, pray at 04:00, clean temple, breakfast then free time to meditate, lunch at 12:00 which was the last meal of the day, more prayers and more cleaning in the afternoon, bed at 19:00.
Oh, and slept on the floor with no air con or western toilets.
Loved it but was only for a short stay.
