I don’t know any cooking classes but if you decide to go the Muay Thai Route I suggest EVO360 in Pattaya, they have a great option for beginners and it’s so much fun
Liam Patel 20,000 included the membership and required paperwork needed, but you still have to pay the application fee directly to the embassy you apply through. No checkins are required and you can go anywhere in Thailand
they provided me with all the required paperwork for the embassy, I don’t believe your required to train at the gym your DTV is through, I know a few people who have the DTV and are travelling all around Thailand to different gyms
