Devil's Advocate - is it possible that as WDW has "evolved" (or at least "grown" I won't argue whether they've actually evolved into something better and start a flame war with a WDW Originalist), they also started coming up with more things for parents to do with small children? Think about it - how many posts have we all read on this very board where someone asks "Is it ridiculous to bring my (Insert infant age) to WDW?" And most of us have responded along the lines of "you have to temper your pace and accommodate for feeding and naps but sure, go, there's lots to do at WDW with a baby AND lots of ways they accommodate people with babies." Between all the meet and greets and character meals and shows and attractions that don't have a height requirement, there are plenty of things to do with a baby or toddler, so more people don't wait until their kids are old/tall enough to go on (almost) every ride and can tell time and can be trusted to do their own thing and "we we meet at this statue of Walt and Mickey at 2:45 sharp, if you're late, you're grounded." Lots of us have been going since we were kids, we've been going as adults before we had kids, we plan trips more than the av-uh-rage bear and we're not gonna let some pipsqueak with baby cankles ruin it for us with their lack of stamina.
I will be honest - this next will be the first that technically we probably don't need a stroller, and we're not packing our own. But nonetheless my wife wanted to rent a stroller so we had a place to leave our "stuff," backpack with emergency changes of clothes, ponchos in case of rain (or water rides), our bottles of water, OTC medications like Advil and Pepto Bismol...and if it so happens that our youngest (6) needs to crash, she has a place to crash. And honestly there will probably be more crashing because this trip, instead of a couple of hours each day at a park followed by down time and pool, we're planning 1 day park commando, 1 day "off" just hanging at the hotel or Disney Springs as much as possible, lather rinse repeat until near the end of the trip where it's like "we're going home in a few days, ride everything, omit nothing!"
But yeah, we're bringing a stroller. It's either that or cocaine for the kids. And quite frankly, after paying for the trip, who has money for cocaine?
Oops, did I type that out loud?
