Hi Sookie, when I did this tour two years ago, I decided not to do the offered Las Vegas show - the ratpack - as it didn't really interest me. I'm glad I didn't! Those who went had mixed views on it. The concierge in the Stratosphere booked some folks into Cirque du Soleil "O", which was expensive around $100 or so, but those who went loved it. About six of us decided to do the show in the Stratosphere itself - it was a tribute act to various US singing stars Elvis, Michael Jackson, Lady Gaga and some others and it was very good and enjoyable. Best of all, because we were staying in the Stratosphere, we got two tickets for the price of one - paying just $20 each instead of $40! I hope this helps.
Have a great hol,
Bob
