Presenters at an IMEX America 2016 session offered these five tips to help keep yours intact and attrition-free. They urge meeting professionals to be upfront about the reasons for having room blocks, attendees don’t always understand why they are in place and communication is key. They suggest to keep selling past the cut-off dates and to fight pirates and poachers by promoting the link on your registration site. They also mention the importance of keeping up to date on what’s happening locally in the area of your event; whether it’s a marathon or another citywide event, it will likely affect your hotel’s room block. And finally, we are reminded to expect housing patterns to change from year to year. Bonus tip: Communication is key!
