I have been to Vegas multiple times, each time a very different experience as it changes so much so quickly.So, just like Jon said, make sure you see everything on the strip, maybe catch a show in the evening; one of the magicians or a music show that tickles your fancy. Last time went (10 years ago by now) I saw Siegfried & Roy (they are around no more, are they?) and David Lee Roth with a big band; "Jump" with a horn section sounded AWESOME!Be reminded that the older strip section (with the famous arm-waving cowboy) is quite a bit away from today's popular section, but well worth a visit.Grand Canyon: MUST. My jaw dropped at the sheer size of it.
I hope you win a Mega Jackpot so you will be able to buy all the DVDs you want..and a place to store them! Have fun, I look forward to seeing what you think of Vegas. I hope to get there one of these years.
