We do love your kids, but the reception will be adult only!
All of the hotels have paid parking options available and are within walking distance of the church. There will also be parking at the church and the reception venue. You probably don't want to walk from the church to the reception venue (although it is only a mile this involves uphill/downhill and crossing the river).
Cocktail hour at the reception starts at 5. Here are some recommendations: Near the reception- -Great Lakes Brewery -West Side Market -Town Hall -Collision Bend -Lindey’s Lake house Near the ceremony- -Masthead -Noble Beast -Winking Lizard -Nuevo (cool location on North Coast Harbor)
