Activity for Laura

Many of my guest are visually impaired, so cards or even large signs with big lists at the wedding won't be easily read. Would it be a good idea to post the seating chart online for guests to see before they travel to the wedding, and/or have a guide...

My wedding will include several guests with little or no vision, requiring invitations, rsvp cards, thank you notes, etc., all in large print, (or in braille, in some cases). Has anyone had experience with this issue before?
