Follow the local people! They usually know the places you’re coming way better than all the tourists! So: if you’re looking for a nice restaurant, search for the busiest one. If you’re looking for a good beach… ask! Also: don’t be afraid to ask lokal people for help. They usually are super helpful, and that way, you can really get to know the country and the people that live in it!
Check your passport’s expiration date. Unfortunaly, I say this based on my personal experience… you won’t be able to travel with a passport with less that six months validity.
