By Louis Ramirez, dealnews Senior Feature Writer From bachelorette parties to business conventions, Las Vegas is one of the country's busiest cities. Whether you're bar-hopping down the Strip or mastering your game at a casino, the city is so busy that there hardly appears to be an "off season." But that doesn't mean a Vegas vacation has to leave you in the red. We've analyzed the past two years' worth of dealnews Vegas hotel deals to find out when visitors can book the cheapest rates, what hotels offer the best deals, and what kind of freebies you can snag on your next visit to Sin City. November Has the Most Deals, But Summer Sees the Cheapest Rates As far as deals are concerned, last November proved to be the busiest month of the year for Vegas sales: we listed a total of 16 deals. (By comparison, the second most deal-friendly month was March with 13 deals.) While the sheer quantity of deals may have vacationers itching to book their trip in November, we suggest waiting until the summer for the best prices on stays; although November sees the most deals, August and September see the lowest rates with prices on hotel stays dropping to as little as $12 per night. The second-lowest rate we saw in 2011 came in May when we listed deals from $22 per night. Keep in mind, however, that these rates don't necessarily apply to the aforementioned months; they were just available to book, usually for a vacation several months in advance. In fact, the majority of those low summer booking rates were mostly applicable to December stays. So far this August, we have seen stays dip to as low as $24 per night. However, currently, the lowest rate we've seen is within an Expedia Las Vegas hotel sale with rates starting at $29 per night at the LVH Hotel and Casino (expires August 31). And, while it doesn't offer the same low per-night figure, Jet Luxury Resorts touts an Editors' Choice offering with this 2-night stay at the Vdara Hotel & Spa (from $142.20, a low by $38; expires August 16); it's the lowest rate we've ever seen for stays at this hotel. (To find this deal, see the top offer on the Jet Luxury Resorts page; when entering dates, choose Vdara from the drop-down "Building" menu.) Hotels with the Best Deals Last year, MGM Resorts and Planet Hollywood were the most discounted Vegas hotels we listed, representing 20 of the 122 deals we listed. However, so far in 2012, the Venetian is proving to be the single most discounted Vegas hotel we've listed, accounting for 14 deals alone while The Palms Casino is a close runner up with 10 deals. Other deal-friendly hotels in 2012 to look for when booking your trip include The Hard Rock Hotel and, again, MGM Resorts. On the opposite end, the Paris Las Vegas sees the fewest deals throughout the year. In fact, in 2012 we've listed just two deals for this hotel. More Than Half of Vegas Deals Include Freebies Vegas wouldn't be Vegas without its sprawling buffets and 24/7 nightclubs. And while most tourists wind up paying for nightclub admission, the truth is, many hotels will gladly pick up the tab for you. To date, 52% of the Vegas deals we've listed this year include some form of incentive, whether it's a buffet pass, drink credit, or nightclub comp. As a result, we highly recommend booking a deal that includes at least one freebie. Freebies can range from nightclub admissions (which happen to be one of the most popular) to discounts on theater tickets. You can also score a restaurant credit, so foodies should take note; in fact, Expedia is currently offering up to a $100 food and beverage credit with 3-night stays at select hotels in Vegas. (Eligible properties include MGM Grand, Mandalay Bay, Aria, and more.) Ready for your trip to sin city?
