We used to go with my mom to WDW, in '04, '06 and '08. In 2004 it wasn't too bad as my sister and son were also with us and she was with them most of the time. My sister is much more relaxed with her touring, unlike me, who likes to have a plan and follow it as closely as possible. Anyway, the next two times my mother (who was in her late 60's) had a hard time keeping up with me and the 3 kids. It got very frustrating for all of us, for her who wanted to just walk and take in the sites, and us who were rushing around to fit in everything we wanted to do. And she is a very active woman, who works out at the YMCA every day, but she either couldn't or wouldn't keep up. Let's just say that our last trip in '10 with just me and the kids was much easier and with less conflict. Again, that was just my experience. I think it really depends on what you want to do and how you want to do your touring of the parks.
