Found this review that says there is no elevators but I don't know personally:
Traveler rating: Five Stars
Kissimmee: Windsor Palms Resort: "Great condo and resort"
Dec 9, 2005: A TripAdvisor Member, Traverse City, Michigan
I stayed in a 3 bedroom condo for a week in mid November. This is a great
resort and I would highly recommend it. The large pool is heated, which is
great for swimming at night and cooler days. The grounds and all the facilities
were well kept and maintained.
Our condo was large and clean. We had a
ground floor condo which worked out well since they have no elevators at
the resort at all. We stayed close to the pool but none of the houses,
townhouses or condos are very far away from the clubhouse. It is a very
short drive to all the Disney attractions and the Sherberth Road short cut
works out well. I rented directly from an owner but everyone I spoke to at
the resort seemed very pleased with their accommodations. Definitely drive
the extra mile up 192 to shop at Publix rather than the closer grocery store. I
would stay here again!
