I'm also one who never went when my kids were small, but here's my 2 cents. A smaller one will make getting through crowds easier for you - and the rest of the crowd. Nothing like ending the day with bruises all over your calves from the few who use them as battering rams. If your son doesn't want to use it, it's easier to haul a small one around than a large one. It also keep you from developing the mindset of "we can just put all our stuff on the stroller." Then you have a heavy, overloaded stroller to push, and all your stuff to keep an eye on. The previous post listed locker prices. None of them are large enough for a stroller, although it's a good idea to rent one if you have stuff to bring (for small children especially) that you don't want to drag around all day. Haven't ever checked into this, but I wonder if there's a way to store a small stroller at the park? Anyone know? I do know you can email Disney through the DL website, and get a real answer from a real person. If you have time, that may help.
