Montengro or southern Albania ? Solo travel

I was wanting to go to Eastern Europe in June-July for 4ish weeks as a solo 22f traveler. This would be very budget friendly as I’m a broke uni student lol

My route would be flying into Rome then to Sarajevo as it’s cheaper all together than flying into any other countries, then mostar- kotor- budva(?)-shkoder-valbona theth hike- Tirana- lake orhid(?) southern Albania (ksamil, himare, sarande) - back to Tirana then home

Okay so I don’t have the funds or time to do everything I just mentioned unless I do it really rushed which I don’t want to do. I will stay in kotor for at least a night because going from mostar straight to shkoder is really messy and takes ages so if I’m going through I might as well, however, idk whether to stay for longer and go to budva as well because hostels are 50-60 aud a night and it seems realllyy expensive, if I do this I would probably cut southern Albania off.

My last and only solo travel trip was 2 years ago and I spent a long time in Croatia which fucked me financially even though it was my favourite place 😭, the main thing that got me were the entry prices into the bars and clubs (I think I actually paid 60€ entry one night) and drinks, which I assume would be similar in Montenegro. I just want to have more money when I come back then last time because I couldn’t afford to buy any souvenirs for myself or anything really.
