Look for value-added deals. Hotels are struggling to fill rooms right now, and they want to entice you in. "They're really throwing things in to the mix to sweeten the deal for travelers," Tornatore says. That could be anything from spa credits to free meals to an upgraded room.
If you don't want to use the spa, that's one thing, but if it was something you were planning on paying for, a free massage can reduce the cost of your trip by $100 or so.
