Bonnet Creek is closer to the parks; it is right next to CBR, and a shorter drive to many of the parks than OKW or SSR. Vistana Villages may well have a bit more to do onsite, though BC does have a small lazy river and a pretty full activities schedule. Non-owners can look at the current activities schedule, but unfortunately you have to navigate to it yourself---it doesn't work to post a link.
Go to the Wyndham VO home page:
www.wyndhamvacationresorts.com
Click on "Explore Our Resorts"
Click on Florida on the map
Click on "Wyndham Bonnet Creek Resort"
Click on "Activities" (on the left hand side).
You can also see some pictures and video of the resort as a non-owner, but not floorplans or
point charts. Those are available elsewhere.
I am also nervous that there are SO MANY people trying to unload their Bonnet Creek Timeshare weeks.
These are most likely "mega-renters": owners with significant Wyndham holdings who have a side business renting Wyndham timeshares. Bonnet Creek is a relatively easy resort to rent, because there is a natural demand due to its location. I've rented my points to friends a couple of times for stays there.
Both resorts are wonderful, and you couldn't go wrong with either one.
