Group rooming list: Rooming lists with complete names are due on Friday, April 19, 2019. Any unused rooms, where names have not been provided by this date, will be released. Please use the rooming list spreadsheet through your Group Block Management Account online. You have the option to upload the list yourself or send us the list to process. To download the rooming list spreadsheet, please log in to your Group Block Management Account online. Please send us a message if you do not know your login credentials.

Group Attrition: Groups must actualize 80% of the contracted block to avoid attrition penalties. For an entire room block cancellation, please refer to your Group Booking contract for details regarding the applicable fees.
