Reservations and Cancellation Policy

• Deposit
  A deposit by major credit card is required at the time of booking. A deposit equal to one night’s guest room rate is required to hold each guest’s reservation. The deposit confirms the reservation for the dates indicated and, upon check-in, will be applied to the guest’s folio. All deposits will be charged at the time the reservation is made.
  
  
• Cancellations:
  Reservations may be cancelled up to 72 hours prior to reserved arrival date at no charge. For cancellations made after the time noted, the hotel will retain the room deposit of one night plus applicable taxes. Please contact the hotel directly if you need to cancel your hotel reservation.
  
  
• Early Arrival/Stay Later:
  The ADEA hotel block rates (see above) are available three days before and after the program dates based on guest room availability.
  
  
• Early Departures:
  An early departure fee of one night’s stay will apply for any individual reservation if a guest checks out of the hotel prior to the confirmed checkout date. During check-in, the hotel will confirm each guest’s departure date. At that time or prior to check-in, guests may change their departure dates without penalty. If an event occurs that requires a guest to depart from the hotel earlier than the confirmed departure date, the hotel may waive the fee.

Note: ADEA is unable to accept or process hotel changes or cancellations.

Check-in and Check-out Times 

• Check in: 4:00 p.m. 
• Check out: 11:00 a.m. 

Guests arriving before check-in time will be accommodated as rooms become available. 

Note: When using a debit card during check-in, your bank will immediately withhold the authorized amount equal to your entire stay plus incidentals from your checking account. It may take up to 10 business days for the release of any holds.
