I'm planning a roadtrip in Albania with my partner (mid twenties) for 6 days in mid september. We will be renting a car. The itinerary i drew out is bold:

We arrive in Tirana at 22:50 and we will sleep near the airport to pick up the rental car early the next morning.

Day 1: pick up rental car and leave Tirana at 08:00 -> drive to Berat and explore for a few hours -> drive to Gjirokaster, explore, and stay the night

Day 2: Leave gjirokaster in the morning -> blue eye -> check-in in hotel in Sarande and have lunch -> go to a beach in Ksamil until sunset -> sleep in Sarande

Day 3: ferry to Corfu early in the morning and explore Corfu the whole day -> back to Sarande for dinner and sleep

Day 4: leave Sarande -> go to Himare and explore beaches nearby -> sleep in Himare

Day 5: go to Dhermi and more beach time (dont know if we should sleep 2 nights in Himare or 1 night in Dhermi)

Day 6: Leave Dhermi early -> do the Llogara pass (possible stop in Vlore) -> back to Tirana to explore a bit and have dinner

We then leave at 04:50 of the next day.

I am wondering if: is day-trip to Corfu worth it? For a couple of our age, is it better to stay in Dhermi or Himare (we want some nightlife also)? Where is the best place for nightlife and partying untill late? What would you change in this itinerary?
