We liked Windsor Hills. We would stay there again in a heartbeat. I believe they have a shuttle to the parks, but it is very limited - I would never stay off-site without renting a car.
Also, on our last trip (March 2018) we rented our minivan through Costco - worked out to just over $33/day ($432.72 for 13 nights). Keep checking as your dates get closer and rebook when lower rates come up. Parking is pretty expensive at the parks (up to $22/day I believe), so you definitely have to factor that in, but we really prefer the convenience of coming and going whenever we want. Driving to the parks from Windsor Hills was easy - it's very close.
