Sirens of TI Show Treasure Island Hotel and Casino offers a free family show with pirates and excitement repeated 4 times nightly. No charge for this entertainment! Pirates battle with seductive (but not upsettingly so!) Sirens who wish to lure them onto the rocks, enthusiastic show with action, song and dance. It's not terribly violent but there are live action scenes, and the Sirens are dressed for Vegas, so please consider whether you feel it's appropriate for your kids before going.
