I hate central European winters and last year, I decided to run away for part of the winter to some warmer places. I spent 1 month in Sri Lanka in March and then 2 months in Vietnam and Indonesia in November and December and it was the best decision I could have done. Luckily I also have a job which allows me to work fully remotely. The prices are extremely low in these countries for EU standards, so you can live like a king there and the most expensive thing is the flight - which you can mitigate if you book early. This year I will most probably do the same thing for couple of months at the end of the year - just haven't decided which tropical country will be the lucky one this time
I am thinking about Sri Lanka again and then travelling north to India.
For the summer, I will stay in Czechia, as I don't see the point of going on holiday during the one part of the year when the weather is nice and you can do anything here.
