I'm going by the op. He wants 5 months in winter ( maybe less) so I'm not sure what other topic the poster I quoted was talking about. I am only adding to what the OP is looking for. No other stay of longer than 5 months. I will also do 60 + 30 , leave a short time ( hopefully it's 60 days exempt in Winter 2026) come back for the 60 days then go back to my home country. Another good thing about this plan is if it's just a 30 day exempt in winter 2026 ( no one can predict this yet) you already have had 90 days in Thailand and come back and do 30 + 30 day extension then back to home country.
