I'm writing you as part of next year's Debconf local team, responsible for accessibility of Debconf 12, hotel and everything related to the venue.
Next week we are going to see the local venue with two persons from local organization working on disability issues. We have contacted them and hope that we can have company of one phisically and one visually handicapped person to evaluate the accessibility of the venue.
But before, I kindly would like you to ask to review the Accessibility Checklist  on the wiki to see what else should we consider in order to take note of it and to get a real impression about the possibilities and challenges for the organization of having next Debconf be a success in accessibility. We will translate this document and study it with the local specialists and hotel stuff.
