Larger stroller or some other option?

Could you use the stroller that you have for the younger one and attach it to a rented wheelchair?

Again, sorry if that's not allowed at Disney. I'm not really sure, just trying to brainstorm ideas for you.

Unfortunately, not allowed at Disney.

Good brainstorming, but not allowed at Disney because It would be way too long.
Maybe suited for outdoors in park or something. Even outdoors, it looks like it would be hard to turn and steer because of being so long and the 'driver' being so far from the front.
