So, pushing a stroller with a diaper bag on it makes me a pack mule? Look, I totally agree that many parents these days coddle their kids (you see a lot of that at WDW). But suggesting that we should just avoid the parks (at a place designed for families with children) or leave half the family at home because it requires we bring more stuff with us is just silly. Sounds like it worked great for you. Doesn't mean its the only or best way. My oldest daughter didn't go until she was 9, and we seriously regretted not taking her sooner. Our youngest is 3, and will be going on her 4th trip in June. I wouldn't trade the memories from those trips for all the money in the world. I get that people who go with older or no kids get frustrated at all the strollers, so I apologize if my family's vacation inhibited your enjoyment in any way.
In all seriousness, congrats on successfully raising some great kids. It sounds like we would agree a great deal on how to raise a family, if not so much on when to take them to the happiest place. Hopefully, mine won't be too much of a disappointment to society after so many damaging trips to WDW.
