How many "personal event chips" have been put out by Vegas casinos, and do you know if anybody has a webpage listing them as-such? I've seen a few of these wedding chips, and I'm wondering how common it is, and what sort of cost is incurred. I'm sure there are time issues, too, as it can't be quick to get something like that approved. Also, I'm wondering if you have to commit to buying them all (and maybe having the entire elaborate wedding on-site), to get a Casino to put them out?
