2006, Imperial Palace. My ex-wife still says the IP smells like dead hookers. We made the mistake of eating at the lunch buffet. I have never made that mistake again. We switched to Casino Royale midway through the trip, and the room there was actually an upgrade from IP. We were young and broke and really did not care though. It was about 3 weeks before the Stardust closed, so I fondly remember gambling there and at the Frontier, since I (correctly) figured it would be closed by my next visit. I have been to Vegas 7 times and just booked my 8th trip last night. My last two trips have been Wynn and Aria, so I have made up for my days of slumming it at IP.
