Well, this will be my first trip to Vegas and I am just wondering why to use Priceline or Hotwire when hotels offers lots of free coupons and free offers if we book room directly? If I use priceline, do I get those offers which hotel have specials? If not, then why we not book directly from those hotel? Example, I have booked one night at Excalibur on June 6th for $61. Hotel is offering me $25 food credit which I can use any of their resturent. Plus $30 casino match play. Plus 2 free spa admission which is almost $30 value. Plus $200 worth of value coupon book. If we take out spa still I get $55 value offer. So my room cost is only $16. And I think that's outstanding deal. But not sure is there any catch 22 with these coupons? As I am going Vegas first time, if someone can help me, will be appreciated. I have noticed that most of the hotels (4 star also) offers these kind of deal. So why not book them directly rather then go with blind offer???? Your feedback will be a great help.
