No splash pools--the townhomes there are larger than the townhomes at Windsor Hills and more upscale, they have a small garage. They are 3 story models, 3 bedroom, 3-1/2 bathrooms in most. Some have 2 living areas instead of the 3 bedrooms, but most have utilized as third bedroom.
Vista Cay is the only short term rental community ever allowed in Orange County to date, other than the condo hotels. There really are no housing communities near Universal.
We went right up I-4 to Universal from Windsor Hills, exit 75, and it was a straight shot, only took us 20 minutes at best. However, with traffic could take you longer.
We stay at both Vista Cay and Windsor Hills frequently. Definitely, Vista Cay is more convenient for Universal and for groceries, restaurants, stores, etc. Windsor is most convenient for Disney and has more housing choices and of course, the splash pools in the townhomes.
There is some give and take! Good luck in your deciding. They are both wonderful resorts.
