I will be traveling to Barcelona for 2 weeks in August with my husband, son and 9 year old daughter. One week my husband and son are going to go to a tennis academy in the area. The second week we will play tourists and see all of the sites. I am trying to figure out something to do with my daughter for the week without my husband and son. I don't want to do all the typical tourist things b/c we will do that as a family the second week. She is a fairly mature 9 year old and a good traveler. Any suggestions?
