Two full days in Vegas, what would you do? [View all]

I'm not a big fan of Vegas, but it looks like I have a 4 day business trip there with two down days in the middle with nothing to do.

I hate gambling so I won't be doing any of that. I'm looking for shows or other activities that are worth seeing. As far as shows go, I'm thinking some sort of comedy or theater would be my first pick, but open to anything entertaining. I'm not as thrilled about seeing octogenarian performers, tribute shows, or magic.

It will be next week so not much lead time.
