Housing Alert!

It has come to our attention that a company named Exhibition Housing Management (EHM) has been contacting exhibitors and offering a “discounted” hotel rate to exhibitors. This company is not affiliated with U.S. HYDRO 2015 or the Gaylord National Hotel.

The only method for reserving the conference rate is by calling the Gaylord’s reservation line, or online using the hotel’s event website listed above (Select “attendee”).

Neither THSOA nor the Gaylord will contact you to make a reservation. Any company claiming to be affiliated with us or the Gaylord is fraudulent.

We do not know how this company is collecting your information, but many conferences and conference attendees have reported these same actions from EHM and similar companies. This is a sophisticated and well organized fraud. Be assured that THSOA is committed to protecting the privacy of our exhibitors and attendees.

If you have questions, please contact John Marinuzzi at

Wednesday , March 18, 2015 - Hillwood Estate & Gardens

Marjorie Merriweather Post bought Hillwood in 1955 and soon decided her home would be a museum that would inspire and educate the public. Her northwest Washington, D.C. estate endowed the country with the most comprehensive collection of Russian imperial art outside of Russia, a distinguished 18th-century French decorative art collection, and twenty-five acres of serene landscaped gardens and natural woodlands for all to enjoy. Opened as a public institution in 1977, today Hillwood's allure stems from the equally fascinating parts that make up the whole. From the captivating life of Marjorie Post to the exquisitely maintained Mansion and Gardens, the experience of Hillwood is not to be missed.

$65 - Travel by private coach & high tea is included.

Book all 3 events for $175
