We went last October when our eldest daughter was 3.5 and our youngest daughter was 19 months. At first, DW wanted to just rent a stroller for the week, but when I researched rentals, I wasn't excited about the offerings. Given them our eldest really hasn't been in a stroller for a while, but realizing that "Mickey's House" was likely to be overwhelming for her, I found the Sit & Stand and we were THRILLED to get it (bought it 2 days before leaving).
The storage underneath is almost useless; however, we would hang a bag over the handles.
We are going back this December and we are certainly taking it again, even though the kids will be pushing the max weight limits.
Good luck and have fun with your trip.
