Looks like I'll be getting one Really Cheap.
Anyone ever use one of these as a stroller for a larger child?
I have one (although without the stroller wheel - we use it on a bike) and I would never, never, never get the stroller wheel kit. If I did get it, I wouldn't take it to Disney.
1) - Check the width. Mine is 36" wide - which is pretty borderline to get through the gates. You'd have to get it lined up just right. Measure at the widest point, which is probably the bottom of the wheels, but may be the wheel hubs.
2) Make sure it's easy to get in and out of. If we left the cover off, DD could hop in and out fairly easily. But even then there's a raised edge all the way around, which is easy to get entangled in if you're in a hurry, tired or not paying attention.
3) See how quickly it folds down. Mine folds down in < 10 seconds, but we looked at one that took about 5 minutes to fold down. Folded down the footprint is no smaller than when it's set up, and it isn't designed to sit on an end while folded.
4) Think about how heavy it is. Mine is around 25lb, and most seem to run 20-30lb. That's a lot of extra weight to shove around all day. It's fairly easy if you have good bearings - but the suckers have a *lot* of inertia. It's also a lot of weight to manhandle to fit into a partially loaded monorail car.
5) Look at the weight balance. Bicycle trailers are designed to center the weight directly over the wheels. With a well-designed bike trailer very little weight rests on the front hitch (or front wheel in this case). If you put things in the rear of the carrier (where the storage space is) you run the risk of an unloaded front wheel. That can cause problems steering and loss of control on hills.
6) look at how the brakes work. The last thing you want is a stroller that's going to roll off when you try to park it.
Now - it may work find for you, but it's something I wouldn't pursue for a theme park. Hopefully that will give you some way to evaluate the limitations before you take it to FL.
