Thank God for Diana and her generally solid ability to organize stuff. We spreadsheet'd all of the event registrations, printed envelopes, stuffed them with tickets, itineraries, coupons, name tags and got everything ready to go in about two hours. Check-in should be pretty smooth. The park is going to hook me up with Internet access as well, so I'll be able to accept credit cards for on-site registrations.
I really need to write that online registration app. I have it worked out in my head how it should work. Just need to write it one of these days. It's hard to prioritize it for something that would only be used at most two or three times a year, but on the other hand, an online based club should probably have online event registration!
