we travelled there from Spain to a monster truck show of which our family is big fans. Never been to Cardiff before but visited the UK back in the early 90's but even so things have changed a lot there, it was for us quite a culture shock.
The Stadium did not come up on our Euro Sat Nav and has no obvious signposting from the main M4 Highway so was difficult to find so be warned.
Also there is a lot of homelessness and poverty in Cardiff more even than in Barcelona which quite surprised us, when we asked people for directions they asked for cigarettes and money in return, you should be prepared for this if you visit.
We saw many children in gangs, no more than 11 or 12 years of age drinking strong lager and smoking pot and they threatened to break our car windows if we didn't give them money, when we asked a policeman for help he said 'welcome to Wales enjoy your stay'
The stadium otherwise was wonderful so was the event but any trips to the UK need to be carefully weighed up its not the country it used to be.
