First solo trip to Thailand for 3 weeks

33/m first solo trip ever. The only definite plans I have is to attend Loi Krathong and Yi Peng in Chiang Mai. I also plan on getting a Sak Yant from where sidewalks end and visiting Ayutthaya as part of that experience. I was hoping for some suggestions on how to best attend the 2 festivals and any other recommendations on things do or places to visit around Thailand. I’ll be there late Oct – mid Nov.

I’ve been to other countries in SE Asia before but with family or friends. I was also hoping on recommendations on where to meet other tourists or things I should avoid. I’ll probably spend the whole trip in Thailand and I’m starting off in Bangkok.

Thanks for any tips or advice!
