Yessss viva the Balkans. Lot of great beaches here, food is cheap and good quality especially in the summertime a lot of great stuff is available. Depending on where you go there are more tourists, English speakers, tourism services, etc. There are a lot of beaches to choose from but hey you could hit multiple towns and/or countries for a more diverse experience.
@XENOCOMPUTERISM For context I’m Bulgarian, visit there myself many summers and all over the country there are a lot of good spots, natural beauty etc. I’ve had friends go to Croatia and really enjoy it. Likewise with Greece but you’ve probably already thought about that. I’ve also been to Bosnia, people are very friendly and speak English too. Albania has also been mentioned when it comes to beaches 🇧🇬🇭🇷🇬🇷🇧🇦🇦🇱
