That's an easy one. Most of the major permanent Strip shows (plus those at the Las Vegas Hilton) -- including O, Lance Burton, Celine Dion: A New Day, Blue Man Group, Danny Gans, Jubilee!, KÀ, Zumanity, Mamma Mia!, Le Rêve, Phantom, Manilow: Music & Passion, Menopause the Musical, and The Price is Right Live -- have online seating plans. So do a few of the smaller Strip and off-Strip showrooms, including Legends in Concert at Imperial Palace and Forever Plaid at the Gold Coast. You can access these from our site by clicking on the "Link" button you'll find on those shows’ individual entries when you use our Shows & Events function under "Vegas Info."
For others, including Carrot Top at Luxor, La Femme at MGM, and Mystère at Treasure Island, it's not possible to link direct to their seating plans, but the link will take you to the show's home page, from which you can access a chart.
Other venues, including Harrah's, Excalibur, Riviera, Rio, Stratosphere, Tropicana, and Flamingo, don’t have available seating plans for their showrooms, and neither does the Aladdin right now, although this may well change once the Planet Hollywood renovations are completed.
