30 years ago the clubs in Pattaya used to be open until 4:00/5:00am they were packed with tourists and locals, people came to enjoy as the did in Bali, admittedly in Bangkok keeping places open so late will have more potential dangers so 2:00/3:00 am would work. A lot of people in the tourism industry work late so having somewhere to let steam off is good, plenty of time to visit temples
