meh, doubt anyone cancels a business trip because of a joke. I was fairly sure she wouldn't be coming as soon as she said she was. I've seen this same scenario play out a few times. Girl plans trip, doesn't get enough pre-books, girl cancels trip.
I don't think there's a big enough market here for someone to pull off a successful trip. There could be but a local would have to spend the time creating it first, though I doubt they would be allowed to. We have far too many cops with too much time on their hands. There isn't a good way to advertise either and most people wouldn't see short term ads in the few ways there are to put them out. People aren't used to professional services being available so they don't look for them.
Me, I look for ads every day cause about once a year the stars do line up right and I'll be damned if I miss it.
