Looking to go to Thailand for 30 or 60 days to train Muay Thai

Hello everyone. So I’ve been training Muay Thai for about 4 months now, anywhere from once to three times a day. I will have the ability starting around February / march (any time after that to) to go to Thailand (financially speaking). I’m going there to experience the culture, and elevate my training. Wouldn’t mind exploring a little bit and doing activities. I saw that some gyms in some places offer in house accommodations. I need some opinions on what part of Thailand would make most sense to go, best gyms to train at with best accommodations. For budget, it’s pretty open as of right now. Of course I would like to save as much as possible but I’m not against willing to spend a little more to get the best experience.
