We recommend catching an Uber/Lyft or car-pooling to the event space. There's two large lots nearby and ample unmetered street parking.
Where Should I Stay?
There're ample hotels downtown, but for us Portland's best exemplified by the neighborhoods on the East Side. We really recommend AirBnBs or rentals around North Mississippi Avenue, Northeast Alberta Boulevard, or Southeast Hawthorne Boulevard. The beauty of Portland's in it east-side commercial districts, restaurants, shops, beautiful houses and gardens.
