We will be staying in Vegas 7/3 - 7/6 and would like to stay at either 1)Mandalay Bay, 2)Monte Carlo, 3)Mirage, or 4)Flamingo. I've seen these on Kayak, etc for 1)$163, 2)$94, 3)$129, and 4)$94 a night respectively. Are all/any of the mentioned resorts featured on Priceline/Hotwire? What's the best way to get a deal on 1 of these 4 resorts using PL or HW? I've noticed the prices slowly creeping up last few days, should we wait until a few days before to get a better price? It seems the dates we are looking at are not busy as I see only a small number of very small conventions going on during this time. Replies/advise appreciated
