I ended up leaving this tour, we stood for 30 mins whilst he talked about the country/city, whilst I find this information interesting, I have done around 15 walking tours, and it's normally done in 10-15 minutes, 30 minutes was way too long to be stood still especially in the heat, it's a 'walking tour', once we got moving, we then stopped 3 times within 150 metres, the first outside of a bustling restaurant so couldn't even hear the guide talk. Also as I said I have done many of these tours, and generally if there is a big group, they split into 2, there was way too many people on this tour!! I have never left a tour before and always found them amazing, very very disappointed as Dubrovnik has been on my bucket list for so long and I ended up going solo!
