Going to Barcelona this summer......?

The host family has asked what I want to do when I visit. Besides the Beach what would interest the typical 17 year old. Shopping is also a personal favorite as well. Also I have to bring gifts for the family.Would this be o.k. ?A yankee candle for the Mom, NY Yankees shirts for the Dad and brothers and candy from Hershey ( I live close by)for the girl I'm visiting.
