If you and your SO are a developers, then I would highly recommend a work-cation in Prague. I spent a few weeks at a really cool co-working space, PaperHub, which was part of the Institute of Cryptanarchy (lol). They take BTC for everything, the transit system is a dream, and there are tiny little specialist grocery stores everywhere. If I was ever going to return to the same place twice, it would be Prague.
Beware of burnout, though - there is no rest in this lifestyle. The home office wants me online during their business day, and constantly learning new cultures is a huge cognitive load. After two years of this, I needed to settle down for a while; right now I am resting between jobs, thanks to a very supportive mother. Oh, make sure to take good care of your parents, they may end up being the only solid, reliable people in your life.
