Great attitude!We were there at the same time and experienced A LOT of the same issues with rides breaking down and big crowds. My advice is make the most out of what you CAN do and if something's goes wrong- make a joke out of it! We were the NEXT group to be loaded when space mountain broke down. We listened to the cast members and figured out that some had thrown up all over the last tunnel of the ride and it had to be cleaned. We waited patiently making jokes and then when the cleaning staff came out of the tunnel we cheered for them and EVERYONE in that last loading room joined in. We then proceeded to cheer on every car that had been stuck on the ride as they came back. Before we knew it, we were on the ride. Sure it cut into our plans for the day but it ended up being a really fun experience! Always expect your plans to change and get your kids in on the jokes! It doesn't matter what you accomplish- just have fun!
