The Freedom Pushchair indicates it is for up to 200lbs, however this will be the larger "jogger style." The Maclaren Major indicates it's for up to 140lbs, but we have that and personally I think 140lbs would be a stretch and uncomfortable for someone that big. Convaid makes pushchair/strollers in larger sizes that I believe fold fairly compactly (described as umbrella-style fold), but I'm not aware of standard rentals for those as they are sized to fit and very expensive to purchase. You might be able to look into purchasing or borrowing a Convaid from home to bring with you if, especially if this is something you'll be needing over time for other vacations. Otherwise, I'd suggest a wheelchair rental, either standard adult size or pediatric size. You don't mention how old you daughter is, or why you would prefer a stroller over a wheelchair. But I think at her size, you are looking at a large stroller or a wheelchair.
Enjoy your vacation!
