Wife.gov and I got married in Vegas in 97. Told all the guests that it was in Vegas and the date, then told them to let us know what hotel they were going to stay in. Called them all the day before and told them what time to be in front of their hotel to be picked up. We had chartered a bus and I rode around Vegas picking up guests while she changed and met us at A Little White Chapel in the SS with the trunk loaded with thee stuff for the reception. We got married on the bus then told the driver to take the guests on a little tour and be at the hall we rented (Unitarian Universalist church) in an hour. We drove up there with a couple of friends in the back seat, set up the stuff we had picked up at Costco the day before (including the cakes) and had the reception there. After the reception, the bus took everyone back to their hotels. A good time was had by all, we didn't have to entertain relatives from out of town, and the whole thing cost us less than $1200 (not including the trip, which we sould have done anyway.)
The kids who want me to wed them have already put down a $600 deposit on the place they want to get hitched. They are trying to pare the guest list down from 250 so they can afford to feed them at a sit-down reception. Oh well, it's their money or credit cards...
I'm a big fan of Vegas for weddings. Pretty much you can do it any way you want, from darn near free at the courthouse (which, BTW, sells licenses 24 hours a day...) to something that would break Donald Trump.
