I'm sure someone will answer about the Resort but I spoke to the Villages last week and was pleased that they do have a free shuttle to the Disney parks but not to the Universal parks. This was very disappointing for me for "obvious" reasons, so I asked if they had paid transportation. They did, and it was $11 a person and only left one time a day and came back one time a day.
I was considering them as a way of saving money on a rental but that didn't work for me, though if I were only going to Disney exclusively, it would.
