I'm doing 2 trips this year...the first in 12 days and doing the MNSSHP and have spent 2 days working on a pirate costume for the party! I'm excited as all heck and now a girl at work has Mono and I'm terrified they will cancel my trip..I have 800 bucks sunk in this outing so far...sheesh....the tickets don't expire but my party ticket will...and I'm not sure about the WDW Birthday Bash Costs....sure hope the trip isn't cancelled..since I'm a contract person I'm not sure they can do it since I told them before I signed the contract I was going..!!!!!!!!!!!!!! Hope you have a blast BUD!!!
