Overall we are planning on this being a kid-free wedding. Some exceptions will be made for immediate family and those traveling from far away. For our friends and family nearby, it would be great if this could be a nice little date night away from the kiddo(s).
The closest hotel to the venue is The Graduate Hotel, there are a couple other in the U District, we'd definitely recommend checking out VRBO or Airbnb. As far as neighborhoods go, we live down in Seward Park, Gavin lived over in Bellevue for many years and Dylan was in Tangletown (a small neighborhood on the border of Green Lake and Wallingford)—we'd recommend them all.
There is plenty of parking at the venue if you choose to drive—you shouldn't have a problem finding a spot.
The dress code is semi-formal. The grooms will be wearing colorful suits with no tie's. Think garden cocktail. Wear sundresses, floral prints, ties optional, nothing fussy. Almost the entire evening will be outside, with the ceremony and dinner on grassy lawns.
The main parking entrance will be on cross streets 36th Ave NE and NE 41st Street. This will be the second entrance to the horticulture center.
