All you need to do is submit a new group request. In the toolbar at the top of your HotelPlanner login, click the link to “Submit New Request”. Or you can let your assigned HotelPlanner agent know about the changes, and he or she will submit a new request for you. A new group request is necessary because rates and availability from hotels are likely to change.
If you’ve already signed a hotel agreement, you’ll need to notify the hotel contact of the change you need to make and have it approved.
