Well I am still my parents "child" (living at home but 22) and when I was 20 we went. I still greatly enjoy it, because it's different. Characters are out that are not usually out, there are new experiences, etc. However, as a complete disclaimer, it can be very, very crowded and it is a hobby for people to stake their spot for the parade like it's their job. So if you want to enjoy the park but also see the parade without having to sit and wait for a long amount of time to see the parade, good luck. I think it's totally worth it, but it can be a pain dealing with the crowds who must hold their spots (which is most of them).
