You want to get married by the ocean, but don't want to have your guests drive a few hours from DC or NOVA? Say no more. The Chesapeake Bay is the answer to your questions. The beauty of getting married by the Bay however, is that you never have to deal with those nasty tides, choppy waters, or irritating bugs! It's a win-win!
The nice thing about Silver Swan is that there is ample parking for everyone (selfishly, I like that vendor parking is easy to manage too!), they have a GORGEOUS outdoor ceremony location (and indoor if the weather doesn't cooperate), and an amazing staff! That last part is crucial! You want to make sure that your venue team is friendly, professional, and most importantly -- has a sense of urgency. And I can say that The Silver Swan has all of that in spades!
If you need a larger getting room, perhaps the guys may want to get ready at a nearby Air B&B or hotel (like here), and manage transportation for your guests. It's a really location, and I hope you enjoy a taste of the pics!
