I am planning a trip during the holiday lull between Christmas and New Year's Eve (12/26-12/28). Many hotels have 4-night minimums for NYE, which makes any reservations that include a Friday very difficult. My $79 bid for 5* South Strip Vicinity and 5* North Strip was rejected. Given the currently available standard rates for those hotels, I didn't think the savings would be worth the risk of having to prepay and not be able to cancel the reservation. A $100 bid would have ended up costing closer to $300 with resort fees and taxes, but I wouldn't be able to cancel. Standard prices are my rough estimate and includes resort fees and taxes: Westin Las Vegas is about $250 for 2 nights, but you have to prepay. Otherwise, it's more like $350. Vdara is about $300 for 2 nights. Vdara is right in the middle of the Strip, next to Aria and Cosmo. Wynn and Encore are about $350 for 2 nights. Really nice rooms. Good option because it's walkable to Palazzo and the mall. Cosmo is about $400 for 2 nights. My personal favorite because it has everything - location, style, convenience. Palazzo is about $450 for 2 nights. Not worth it. Mandarin Oriental is about $600 for 2 nights. It's the best hotel in Vegas. Right in the middle, next to Aria and Cosmo. Aria is about $650 for 2 nights. Not worth it.
