Hi Everyone,
Our recommendation is the Hotel Continental on Las Ramblas. the weblink is www dot hotelcontinental dot com. choose the Hotel continental Barcelona. We loved the access to taxis, buses, the metro and those hop on hop off tour buses. Our daughter's favorite thing was the 24 hour snack bar. We found this hotel from watching Rick Steve's travel series on the PBS channel. We also purchased his Europe for the TA and Med in 2007 we took and it helped us find lunch in great local places.
Don't forget the hotels in Europe aren't controlled to only booking a year out! Some hotels book up to three years out......
I hope this helps.. I also will check with a couple other diser's who are not on this trip but stayed in BCN after the cruise. If memory services me right, the one Disney hotel in the marina was not good for the Disney price they paid.
