I'm working to take a Vegas Vacation in the next 2 months (May 28th to be specific) for about 4 days, and I'm looking for the best way to book it. Should I go with a travel agent, should I go to one of those Travelocity or Priceline websites, or is there another method I should go about. For reference, I'm going to leave from Chicago Midway or Chicago O'Hare, and will be staying through June 1st. Thanks!!
