We have always booked our hotel reservations directly with the hotel thereby making certain that our room is exactly what we want. But I see that what appears to be exactly the same rooms can be purchased at a discounted rate using one of the above mentioned sites. Are these rooms in a less desirable location within the hotel? How does this work? Will the hotel match these prices if you call directly? Can someone please educate me on this. I would certainly like to save the money.
