Hotel
We love the Kennedy School! Stay in the hotel (just over 1/2 mile from the wedding venue), have dinner and drinks in one of the bars or pubs on site, and relax in the soaking pool! McMenamins is a staple in Portland, so definitely check it out if you can - even if you don't end up staying there!
Hotel
Another McMenamins hotel! This one is more affordable than the Kennedy School, but be advised that most if not all rooms have shared bathrooms.
