We will be variously staying in our rental RV, at the Golden Nugget, at any hotel we happen to like that gives us a walk-in deal... and the Mandalay Bay on Sunday (we're splitting the Vegas visit, going out to the Grand Canyon on the Thursday and Friday.
The Elvis wedding just seemed like the ultimate silly thing to do. We were actually considering getting a dwarf Elvis impersonator but he was too expensive. Pirate costumes for guests aren't compulsory
We aren't going to the US solely to get married, there's also hopefully some filming going to go on as well.

And the chance to meet up with all these old online friends I've had forever.
