We are one of the first members, 1991 and have not experienced "burn-out", in fact if anything we love it more every year. Honestly I had my doubts way back because my kids were very young and I figured they would start to not want to go when they became teens and beyond, but it never happened. I really believe it is because we don't experience the same type of vacations that we did when they were little. You all know what I'm talking about, the characters, character dinners, breakfasts, etc. We changed our "style" sort to speak as the kids got older. We haven't been up early in forever (well, I guess I should count last August when my daughter and I did a Keys to the Kingdom Tour and were in MK for the opening, hadn't done that in YEARS!), we have our favorite restaurants and make dinner a major event. We are always the last people in a restaurant. I have found that this is my favorite time with my family, whether it's at Disney, on a cruise, or other type of vacation. We seem to really connect over dinner and in today's busy world with all of us going in different directions all year, it'
s something I treasure very much. We ride what we like, take our time, and laugh at all the commando people running from one thing to another. I'm not saying that this will work for everyone, but I wanted to give another view. Families are all different, some won't continue to enjoy Disney as much as mine and that's ok. I think my kids grew up thinking that Mickey and Minnie were their relatives and they honestly think of Disney as their second home. I also think that because my brother and his family became Disney nuts too (they now own a vacation home near Disney) we are all one big happy family and all of us enjoy spending time together. I look forward to the day when I can take my grandbabies to Disney and do all the character dinners, etc. all over again!! The bottom line is that whatever works for your family is just fine. I think the key is to find something somewhere where every family member can enjoy themselves. In the end it's the time you spend together NOT where you spend it. It can be in your won backyard.
Enjoy The Magic!!
