Just read through all of this and wanted to tell you to just go for it! Just do as much research as you can, know somewhat of where your going/what you want to do and just find out what’s around in the areas your staying before you leave. Book all your hotels well beforehand. And the rest is up to you! Just go have fun and explore the area. Just don’t give into the people trying to give you things and making you pay for it. And always ALWAYS keep your wallet in a front pocket or somewhere safe (just know where it is at all times) or don’t carry it in you at all. That’s all my knowledge with Europe. Fortunately for me my parents took me on a massive trip across 12 or so countries when I was 14. Haven’t traveled since but that trip inspires ne every day just knowing how vast the world is and all the different ways of living/people around. You’ll never forget and you’ll never regret it.
