I'm a DC-resident, planning my wedding in Portland. FMIL is "hosting" the rehearsal dinner after the rehearsal in Downtown Portland. Instead of having all the party cart down to her place in SE Portland, she thought a Tom McCall park would be a good place for a laid back BBQ. The official web site does not list picnic spaces and the city web site does not indicate it is possible to reserve space. Any other ideas for a park or similar budget-friendly space for a relaxed rehearsal dinner for up to 30-40 people?
