Barcelona Suggestions

We're leaving for Barcelona tomorrow with one of our school groups. I'm looking for suggestions for stuff to do. We've been there a couple of times and have seen the main sites: Guell Park, Dali stuff, Sagrada Familia and Barcelona Cathedral, la Ramblas, la Bouqueria and the Olympic sites. Any suggestions for something new and exciting in town? Anything to get away from shopping with the wife. We'll probably be hanging around the la Ramblas area just to check in with the high schoolers from time to time.

And I hate the beach so that's out.

You hit the main sites but how about a Bullfight or a Futball match at FC Barcelona?

Cheers

Botanical garden on Montjuic. It's petty cool and offers spectacle views of the harbor.

Also find a place to watch the Euro cup final (spain vs italy/germany)this weekend. Should be a great experience.
