Would you recommend Slovenia or Albania from Croatia?

Hello! My bf and I are going from Miami to Croatia this summer. We are landing in Zagreb then heading to split and the national parks. We have a 14 day trip and want to explore another country while in the Balkans. What drew us to Croatia was the beaches, nightlife, and culture.

Now we are trying to decide whether to go to Albania or Slovenia. Since we live in Miami already we are used to warm weather and the beach, I would like to see something else perhaps like the Albanian alps or lake bled before going back to the coast. I’m unsure where to stay in either of these countries or what there is to do. We like swimming, hiking (not more than 2 hours each way) ruins and cities. Albania seems appealing because of its low prices. I wanted to know which country you would recommended and why?
