Compared with other online travel booking rewards programs—such as those from Hotels.com, Vrbo, and Booking.com—Priceline's VIP program stands out for rewarding bookings across multiple travel categories rather than focusing primarily on accommodations, making it a useful option if you regularly bundle different parts of your trip. Express Deals and VIP Deals offer great savings, but they work a bit differently: Express Deals offer up to a 60% discount automatically on rental car companies, hotels, and flight carriers—but the catch is that you won't know the hotel name until after you book.
