If your date's name is on the invite envelope, then yes! If not, then unfortunately no. We'd love to keep it with just the people we explicitly invite.
The dress code is casual, just don't look like a bum :). We will look FANTASTIC.
Kids are certainly welcome! There is a ton of space for kids to wander and play, so bring them along if you'd like.
Hotel recommendations can be found in the travel tab above. However, you are more than welcome to find a different place to stay. There are lots of hotels, airbnb's, vrbo's, etc. in Seattle and on the peninsula. We both love the smaller cities outside of Seattle, like Bothell and Edmonds.
Yes, there is parking onsite.
