Hi Pat! The reason our exclusive hotel offers are up to 83% off the retail rate is that the resorts are sponsoring the discounted promotion in exchange for meeting the eligibility requirements and attending the no-obligation resort preview. Over 1 million customers have taken advantage of Booksi's discounted vacations and our customers on average save over $2000+ on our all-inclusive vacations. Here is a short video explaining why Booksi's vacations are up to 83% off. https://booksi.wistia.com/medias/4at41l86hi, for any further information, feel free to contact us at support@booksi.com
