I'm in the process of booking tickets for Casa Batllo and Casa Mila (La Pedrera) in Barcelona and noticed that only the Gold Priority ticket, which is a lot more expensive, says you get a Fast Pass (skip the line). This is confusing as I assumed that buying a ticket in advance online for a designated time slot meant you would get access during that time period without having to wait in line. I had planned to but the Blue ticket (entrance + smart guide) but don't want to have to stand in line. The tickets for Casa Mila also mention a different entry policy for the Premium ticket.
Can someone who has been there recently please clarify this for me?
We want to do Casa Batllo and then Casa Mila (La Pedrera), which are near each other (6 minute walk on Google maps) and am trying to decide how far apart to book these two. I've currently allowed two hours on my schedule but the Casa Batllo site suggests an hour is enough. Could I bump up the Casa Mila visit by a half hour, or will there be other interesting sitesd nearby (other than viewing the exterior of Casa Amatller, next door to Casa Battlo) if there is some free time after Casa Batllo?
Thanks for your help in sorting this out!
