Refreshments and Transit

All conference registrations include access to the morning coffee breaks. Meals are not provided for the conference as a part of your registration fee. Some ticketed events (i.e. field trips, closing social) include food as part of their additional registration fee. 

Attendees that booked their hotel rooms thru Travel Portland, ESA Housing Bureau, will receive a MAX Light Rail pass for use during the week of the conference. These will be given out on-site when you pick up your registration materials.

Guest Registration

A $50 guest fee is assessed to register an adult (age 18 and up) accompanying a registrant at the meeting. Youth guests (age 15-17) may be registered at no charge. Family or friends of the registrant who plan to attend non-scientific portions of the meeting program (social events, field trips) are welcome to attend as guests. Fees to register for individual trips or social events also apply for guests. For example, if you and one guest are both attending a ticketed mixer, you’ll need two tickets. Anyone who plans to attend scientific sessions (oral sessions, posters, workshops, special sessions) should not register as a guest.
