My Fiance and I are getting married on Whidbey Island, a popular Summer day trip near Seattle which requires a lovely ferry ride. Unfortunately, there will most likely be a 2 hour ferry wait leading up to our ceremony and many of our guests wont know this if they decide to drive on the ferry. There will be a full warning of this on our website along with tips on how to make things go smoother and faster. But is there a proper place inside the invitation to include warnings about such transportation issues? Or should we just hope everyone will visit the website.
