I have booked a trip for two nights in dubrovnik in summer. I reach there during the day on the 17th May and depart at night on 19th. so I would say it gives me around 2.5 days? Is it possible to squeeze in a day trip to mostar in that time? are there any cheap tours? most of the ones I found online are around 50 GBP per person. Is it possible to go on our own by bus? I checked the bus schedule and looks like the timings arent very frequent.
