I too love Barcelona, but can't add to the things already mentioned. A lot depends on the weather - we went once in the Summer when it was so hot we just did museums, shops and galleries as it was too hot to walk around outside. We were really lucky to catch a flamenco dance group in one of the squares one evening (lucky for me, MrA didn't feel so lucky ). We went later in the year for a few days and it rained one day but the other two we spent just walking around looking at buildings, and people watching from cafes. We each wear a slim money belt under our clothes with most cards, passports (if needed) and money in, just keeping a small amount in pockets split between us. When we visit a loo we get a bit more cash out. We have a card with quite a small credit limit that we keep for travelling mainly. Have a brilliant time.
When did UK governments lose their way?
More limericks with very strict rules and I'm standing by with a metre stick ;)
