Comment Really the trend is moving away from 3rd party (Score 1) 3
As someone who does a fair amount of work travel it really has become preferable to book through the hotel and airline sites than use Priceline or Expedia. Hotels generally don't give you rewards points, they won't handle issues at the front desk (you'll have to call Expedia) and as mentioned the policies are different. Most hotels will honor the price rate a 3rd party site offers as well if you ask them to.
