Thanks both of you. Yes, I will stick with the rental stroller, as it has always worked perfectly in the past. And as I say, our experience has shown us the Swan is the best location for our needs. We thought about bringing someone to help, but that's not an option this trip.
It's an eight day trip, so we have lots of time to prowl around.
The suggestion about sitting behind is interesting - my first thought was I would sit in the one ahead so I could get off first and assist the kids when it's their turn to get off. Of course there are Disney staff for that too. Maybe I will try both.
Cheers,
