The cheapest way to book a hotel depends on your situation. It is cheaper to book directly through the hotel if you have travel or loyalty points you would like to use to cover the cost. If you’re booking last minute, want a travel package, or love snagging a mystery deal, you’re better off going through a third party booking site. For example, you could use our hotel comparison tool. Having said that, you should always contact the hotel directly and compare their pricing to what online booking sites have to offer.
