  For hotel reservations at the Hyatt at the group rate, our contract with the hotel says you may cancel without penalty up to 48 hours before your scheduled arrival date. For Royal Park, there is currently a one-night penalty, but we are negotiating with the hotel to see whether the penalty can be waived. Please contact your hotel as soon as possible to cancel your reservation to avoid further penalties. A simple way is to check the email confirmation your received after your hotel reservation, where you can find the link and instructions of how to cancel your reservation.
  
  We are sorry for the great inconvenience caused.
