The good thing about the UK is the summer and the bad thing about Thailand is the rainy season. Luckily these both happen at the same time, so it might be worth thinking about spending half the year in Thailand (in the UK winter) and half the year in the UK, in the UK summer. In other words, don't spend more than 180 days in Thailand per year, then you don't have to worry about this.
depends where you live. Not everyone has an immigration office on their doorstep. But even if it was just 2 hours, I'd still rather take a vacation out of Thailand. I wouldn't want to give any bureaucrat more than a second of my time if I don't have to. You do you though 👍
it's not a stupid answer at all. I would much rather have a weekend break out of Thailand every 6 months, rather than have to deal with immigration in an office all day. Fair play if you enjoy wasting your time.. that's cool too.
