Aye
Did a stadium tour, had a couple of night outs and went out and about around the town though as well. Such an amazing place, the city is football mad.
I could really fancy doing that - was it easy enough to navigate around town/get tickets?
Yeah, an absolute doddle. Getting tickets for the game is the only stumbling block as they always sell out so we had to get ours from Viagogo and ended up paying 2x the price, well worth it in the end though. Towns are signposted well and the train ticket machines all have an English option. Everyone over there spoke decent English as well so communicating was easy enough as well.
If you ever do think about going in the future it worked out cheaper for us to fly to Dusseldorf and get the train from there to Dortmund so might be best to price that up as well
