Awe I'm about as glamorous as a ponytail in a baseball cap honestly. I guess I do shine up kinda purty though and my dancin shoes haven't been dusted off in quite some time...
HELL YES on the Beatles show; I actually had the chance to see the 300th anniversary show back in September before I came back to Austin; spectacular show; my second time to see it!
All of the Cirque shows are pretty impressive, and all are located in major hotels on the strip. Ive seen them all at least twice and would go back again...
And tickets are fairly easy to come by; check at the concierge desk at your hotel and ask...
