When your offer is accepted, your price is locked in and you may stay at the hotel during the dates specified for the Silent Auction (review your confirmation email if you're not sure, see below). Because this is an auction, your preferred dates are not guaranteed but you may request alternate dates at the time of booking.
You will receive an email at the address you entered when you made your first offer. One business day later, you will receive a second email that is a "Private Offer" with a link to complete the purchase of your auction and start the booking process.
While you wait for the Private Offer email, do not contact the hotel directly. Reservations made directly with the hotel will not be honored.
