Our wedding is a week from Saturday and we are planning an outside wedding at a lakehouse at Put-In-Bay. We understand that since it is an hour drive from Toledo and hotel rooms are not cheap along with the cost of the ferry ride and other expenses on the island some people won't be able to come, but we sent invites out with plenty of time for people to RSVP and still a large number have not responded at all. Of course we need an accurate count for food, tables, etc. What is the etiquette for this? do I call them? I don't want people to think they HAVE to come but how hard is it to RSVP???
