Thanks everyone...
Excellent advice/information.
Yes, we love BCN as well. I'm still trying to figure out what that gondola thing is that goes up to a castle in the sky--ha! We went there in May of this year but the que was soooo long we didn't have the time to wait.
It kind of reminds me of the Eiffel Tower in that there is a restaurant. And, like the restaurant in the Eiffel Tower, it appears that it may have its own designated elevator to eat there first, then on to the castle.
I will start posting queries on the tripadvisor forum in the near future. We definitely want to do this when we return in October.
Thank you all for your time and consideration.
