Things to do before I leave

I have been making up a list of what I need to get for my trip to Las Vegas. It is kind of scary how much I have been discovering I still have to get. Stuff like a new pair of nice looking black slacks and some kind of shoes that will work for the events I will be going to at the Tao and Hard Rock cafe. I also have to run a test run for how I get my laptop to log into wireless access points at places. I have never had any experience with that - must do online research. I know there are several hotspots in the area, but I have no idea how to use them. LOL
