I recently bought an online deal for a Vegas hotel of $120 a night. But when I checked in, the clerk said because I was a senior, I could’ve paid just $99. Are those sites giving out wrong info to make money? MCJ, Atlanta GA

A: Of course online agencies exist to earn money. Sometimes their prices are lower than booking direct with hotels. It’s a matter of timing, season, special promotions and other ever-changing factors. When checking in, always ask the clerk if that’s the best price. Of course, also mention you're a senior, frequent visitor and/or other positive fact. Chances are, you’ll get a lower price and/or other benefits, such as larger rooms, free meals and entertainment.
