I have to admit, when my brother and I were 17 and 19 and went to Daytona Beach for 2 weeks with our parents, we did not want to take a side trip to WDW with my Mom, although she begged. But just a temporary lapse in judgement. Now, we are all DVC members, AP holders, etc. (at 35 and 37). My brother honeymooned there last year for 16 nights (and even invited me, my Mom and my 4 yr old twins for a few nights; we went!!) One of our best trips is when my brother and I went with our parents at the age of 25 and 27; all adults and we had a blast!! My brother and his wife go 2-3 X per year and they don't even have any kids. You are never too old!
