DMJen and others who get grief:
I'm 46, my wife is 48, and we've been on 5 Disney cruises, just bought 116 more points, and I think we've been at WDW 6 times... not sure on the number; I've lost count.
Honestly, I don't really recall any of our friends giving us grief (several of them have travelled with us!) and family? Well, some go by themselves, and some have travelled with us, too! However... if someone says something to you, you can either be nasty and say "Why? Jealous?" or you can just shrug and say "Hey, we like it there" and change the subject.
Personally, I vote for the second option. My wife and I always make our own way - we've done things like historical re-enactment, spending time on the Freedom Trail in Boston, and other non-standard vacation things, and frankly I don't have time to listen to what criticism others may have of our choices. I just shrug and tell whoever that it's our choice, and we had a blast.
GO to Disney! ENJOY it! It's a great place to have fun; and you don't have to be a kid (my wife and I do NOT have children, but we babysat our niece & nephew while my SIL & BIL had fun at WDW one evening) to enjoy it, either!
In fact, another nephew is getting married next year - he doesn't know it yet, but we're giving him & his lovely fiancee a trip to Disney as a wedding present. I hope that they go for their honeymoon... I want pix of them wearing mouse ears.
