i would say it depends on what you plan on doing whilst not training? im also goin back in december for 3 months, you dont need a lot of money for food as the restuarants around the camp are really cheap. personally i would say you can easily live on £10 for food & fluids (not including alcohol ). hope this helps a bit?
Food
100 Baht per meal. Three meals a day: 300 Baht (Thai food is cheaper than Western food).
Trasportation- scooters and push bikes
Most students rent scooters to get around. We also have push bikes available at the gym.
Scooters: 150 Baht daily. 5,000 Baht monthly (price can vary depending on the type of scooter you choose, gears or automatic). You can find cheaper scooters for rent at other places but these often lack the proper maintenance and usually are unreliable (always check your front and back lights before you rent a scooter). If your bike has bald/old tires then you will be prone to getting punchers or slipping. Often the cheaper scooters end up being more expensive in the end.
Warning
If you plan to rent a scooter or ride on the back of a scooter in Thailand then you should ensure you have travel insurance! Hospital fees for motorbike accidents in Phuket can easily cost you up to 10,000 USD.
Entertainment
500 Baht per day is enough to cover you for basic living expenses such as food and water and some basic entertainment such as a few beers at the end of the week.
1,200 Baht: Ticket to watch the fights at the Boxing Stadiums.
1,000 Baht is the cost of a good night out at a night club.
3,000 Baht per night out if you plan to drink and party a lot.
Hey DJ this is cut and pasted from another part of the website. This guestion gets asked allot over the years and always varies to the individual and how much you choose to spend on food and extras!! Hope this give you a better idea!
