Be sure to consider accessibility for all of your guests right from the start...
Use language that encourages guests to include any special accommodation requests with their RSVP- if the event does not require pre-registration, include an accessibility statement and contact information for where to direct accommodation requests
Include parking maps that point out the closest handicap parking spaces, wheelchair ramps, etc.
Be aware of tools such as the Communication Access Request Form from the Disability Resource Center (DRC) which allow guests to request the services of an interpreter and speech-to-text technologies such as CART/C-PRINT
Lamar Univerisity's Disability Resource Centeris the authority on accessibility and inclusivity, and should be contacted for all of your questions regarding procative accommodations for your guests.
