Does booking through Rialto cost more than booking with the hotel?

Yes. Connect Rialto to Claude or ChatGPT with our AI hotel booking MCP server and ask for rates. You finish the booking instantly on a secure Rialto page, direct with the hotel.

What is the value of the VIP benefits?

How does this compare to other programs, like through AMEX Fine Hotels & Resorts, or Chase Edit?

Using a hotel's own VIP program may provide higher upgrade priority, additional VIP benefits and promotional rate offers, and a direct relationship with the hotel for special requests. Rialto offers more VIP hotels than any credit card program. In addition, Chase Edit rates can be substantially more expensive as they rarely run promotions whereas AMEX rates are often comparable but do not offer programs such as Upgrade at Booking.
