I am interested too. They have insane deals on there often, but when you google read reviews on bookit.com themselves and their service, I cant say I have heard a good one. Its all Beware, scam da da da. It may not be, but it sure has turned me off from using it. I would be very careful, and I am glad your asking first. I was also going to book a trip to Vegas 2 years ago, and at the end when you went to pay for your package they added on extra "FEES" of several hundred on top of all your hotel and flight fees for extra processing or something. I am not sure, but it wasnt optional and it jacked the price over a different package I could get elsewhere for cheaper without those hidden fees.
