I was on the Fantasy the last week in April this year and got onboard around noon. Went straight to the line for these tickets and the line was long, wrapped around to near the BBB entrance. Waited maybe 30 min. Got tickets for the first sea day for 1p princess first then 2p for Elsa/Anna. Princess is in the Atrium, E/A in AP. They had staggered times for these events. I'm thinking that if you don't care for these events to happen early in your sailing, you don't need to wait in the long line early. I'd like to hear from someone on my sailing who had princess & E/A tickets for the last sea day and see when they got their tickets, to compare...
