I'm 66, and my first trip was in 1972, my high school graduation gift. (We stayed at the Contemporary). Since having my son (now my grandkids) we go once or twice a year. Though I had made it my roll to pretty much sit out and babysit the child who was too young/small to ride a particular ride, or for nap time (I have motion sickness) I ride everything except some of the more intense motion rides, such as MFSR ans sadly, FOP. I also have slight difficulty getting out of the logs in Splash (knees). I have started using Sea bands and ginger gum, and have been able to ride Space and Thunder Mountains. I have noticed I'm slower than I used to be (we would hit the ground full on power walk), it doesn't in any way diminish my enjoyment. I am happy just being there. Sadly, we have had to cancel this year (I would be arriving today) but we have rebooked for next year. Fingers crossed! I would say that if your body is capable, you can do anything you wish there. I used to tell people that those who grew up going to amusement parks would sometimes be disappointed when they went to Disney for the first time (especially teens) because they were used to thrill, fast, roller coaster type rides, and Disney, was more of a "Look and see", an experience, You would be immersed in the experience, not zipping around at 50 miles an hour. That's how i still see Disney; as a magical experience that you can immerse yourself in.
