We are a family of 4 visiting Barcelona for the 1st time beginning June 10th! We want to visit Casa Batllo. I have 2 questions.
1 How important are getting the 'gold' tickets?
2. Tickets for the 4 of us are for 9am cost 168 euros VS 9:45am cost 144 Euros. I know it would be less crowded at 9am! Is it worth the extra money for the 9am time?
