Taxi for the day was 100 euros plus tip. Takes you to all the sites.
Did the HOHO around the entire city. Plenty to see and do. Gaudi anything was amazing. Aquarium was nice. Tapas were great.
Get to the old city and walk the wall and the town. Beautiful and fun.
Very expensive. 420 euros for the taxi/day split it 7 ways. Pisa is nice. Great shopping in Florence, if you're into that. Florence is a beautiful city.
Taxi for the day. See all the sites. Not expensive.
Amazing. Just get lost and get to St. Marks Sq. Go now ... go often.
