We're going to Butlins in Bognor in Oct with our 2.5yr and 10 month old DD's and I need some advice regarding B-Line passes. Are these a must have? I've read some reviews that make me think we need them but I'm not sure our DD's will let us stay late enough to enjoy a show. What time do the shows usually start? Is there a kids disco or something similar on beforehand? I'm happy to pay for the passes if we'll get our use out of them, but if there's separate entertainment on for the kids beforehand I can't see us making many shows. Any advice would be greatly appreciated. And any tips! Thanks in advance.
