I actually just redeemed for the "O" ticket. Luckily we can do the 10 PM Wednesday show. Horrible limits, Weds. & Thurs., only 10 PM shows. I looked at Zarkana and thought it was much less limiting, almost any show time or day. But I did notice a limit of one per Myvegas account for the "O" ticket. Not sure for Zarkana, after you click the next button it'll tell you terms and conditions. So I'll have to purchase the 2nd ticket when I call the toll free number. I've actually been trying to get the Steak dinner at Excalibur. I can only attempt on weekends. I've clicked the green "next" button several times only not to fill out the form quick enough or my computer/connection is too slow. It's a totally idiotic setup. Why do they care how fast you can type and fill out the form? Once you've clicked the button you should have several minutes to fill out form. Anyway, I settled for one Cravings buffet at Mirage and drinks at Lilly Bar before "O". Like Mick said, "Can't always get what ya want....."
