Barcelona Spain, Gaudi Park Guell ~ when I first saw Gaudi's work in person I was over awed! I could have stayed at Parc Guell all day! Should be on anyone's top 10 list of places to visit in Barcelona!
Must do: Blue Grotto in Capri, Italy. When you go to Naples, you can also go to the Pompeii ruins, or take a Ferry to Capri. Capri is not to miss. The Blue Grotto is the big tourist attraction there, and we thought it was a bit touristy.
