Yes, they're shopped. I've done three of them so far, and am hoping to be assigned to the new So Cal one the next time I'm out there with kids. Sign up with the companies that do amusements, since that's what this is. You will be busy the entire time, but your kids will have a blast. Read that again. You're not on vacation; you're working and there is a LOT to do. You need to write well. That's the biggest complaint from the client, apparently. Write a lot, write well, proofread, and try to see it from their point of view. They're looking for ways to improve. Telling them how great they are doesn't really help unless you're describing, in detail, a particular employee.
This scheduler is great! She is one who explains things in detail and is quick to respond if you have questions. Good luck!
Now scheduling travel shops for the day after Christmas through mid-January.
