We are in the early planning stage for a trip to WDW in June 07. There will be 7 of us. My brother's family (8 yr old), it will be their first time. My family (14 yr old) who visited 2 yrs ago and our mother who is diabetic and will be celebrating her 75th birthday while in Disney. She will need a wheelchair for all of the walking. Any advice for this diverse group is appreciated. Which Disney resort is most convenient for someone using a wheelchair? Anything that we could plan for my mom's 75th birthday? Advice on renting wheelchairs, etc. Thanks
