Facilities Usage Fee

Where to stay?

We know that, for many attendees, finding the lowest possible hotel rate is paramount, and we are aware that often people choose to stay on the outskirts of town and then choose to drive to the conference each day.

However, before you book your hotel room for the ASHS Annual Conference, we want to mention the following ....

The American Society for Horticultural Science continues to make every effort to keep costs at a minimum for those attending the ASHS Annual Conference. One way this is done is to make a commitment to the host hotel(s) that a specified number of hotel rooms will be occupied by our conference attendees. In exchange for the hotel room occupation, the property provides ASHS with complimentary meeting space and other discounts.

The $250 Facilities Usage Fee will apply only to those who register (including exhibitors, speakers, students, etc.) for the conference, but choose not to stay at the host hotel(s).

We encourage all conference attendees to avoid this Facilities Usage Fee and stay at the host hotel(s). Please be aware that if you are sharing a room with another delegate, both names must appear on the room reservation by the hotel reservation cut-off date, otherwise you will be assessed this fee and obligated to pay it in order to pick up your registration credentials.
