Please be aware of, and report, any unauthorized solicitation to Kim McLaughlin at We do our best to keep our eye on these offenders.  We send them cease and desist requests and then report them to the Federal Communications Commission (FCC). Please note that rooms booked through any other source are at your own risk.

Health and Safety

Throughout the COVID-19 pandemic, the focus at HMP Global has been the health and safety of our customers, staff, and communities. Vaccinations have reduced many of the COVID-19 guidelines/mandates regarding face masks, social distancing, and travel. In many states and cities, guidelines are still in place, including vaccination mandates, while in others, guidelines/mandates have been completely eliminated. 

As HMP Global moves forward with producing live meetings and conferences, we will continue to monitor the continually evolving guidance released by the United States Centers for Disease Control and Prevention (CDC), the event venue, as well as all federal, state, and local government mandates, to provide an environment that is as safe as possible for all event participants.
