Our wedding and reception at Lake Union Crew was perfect. The setting on Lake Union was beautiful. The facility was warm and inviting. The staff at Lake Union Crew were very helpful and accommodating. It was a wonderful day, and the people at Lake Union Crew contributed greatly to it.

This was a beautiful venue and perfect for our wedding. Your family and friends from out of town can see a hotel banquet room in their own town. This allowed our out of town family and friends to see how beautiful our city is and provided a great backdrop for our wedding. The staff was nice, accommodating and flexible. Which helped to pull together our DIY wedding. We wanted a DIY wedding to keep costs down. Beware if considering DIY. it is easy to spend what you could have spent with a full service location. We ensured that our vendors were familiar with the location to make it easy, the building setup has some things to consider for deliveries (narrow walkway/dock & entrance stairs) and amplifying sound on the dock (wireless microphones and staging speakers for ceremony music etc.).
Better for 100 or less guests, capacity is 140, but the guests will be standing mostly. I had about 90 guests and it was pretty full with people and tables. Perfect for me, it felt intimate and cozy. The ceremony was on the dock, which worked fine for almost 100 standing guests (no furniture etc) Careful not to crowd together or dock sinks a bit and your toes get wet. It was more funny than an inconvenience. Just par for the course. :-)
Note that you can charter the place as a "vessel/boat". I did not, but it is a cool option. A movable houseboat! Book early, dates go fast, we booked almost a year in advance in a down economy. We had our choice of dates, but had we waited any longer that might not have been the case.

W arrived via a friend's boat and were greeted by our adoring guests from yhe dock and upper balcony. Out of town guests, and really everybody, enjoyed being on the lake, the view and the sunset. Our experience w luc staff was that they were nice, v accomodating, and efficient. They helped with everything we needed and have great recs about other vendors to work with. I love the feel of their big room and it was just the right size.
