When you scan internet and TV ads for Sin City hotels, some are listed for as low as $25 a night. However, quoted cheap rates in flashy ads don’t include the inevitable add-ons, such as taxes, resort fees and other unexpected charges. Often, when checking out, you’re in for a surprise. While booking with a travel agent or online, before making your Las Vegas hotel decision, be sure to request the actual total amount you’ll have to pay.
