We stayed in Dukeroos through Florida Sun Vacation Homes back in November. It was our first time off-site so we did have our worries about going off-site. However Florida Sun was great and delivered on all that was advertised. One fine example is that they said our unit was 75 yards from the main clubhouse/pool area. They were bang on with this, and overall we had a great stay there. Also Windsor Hills was not to far a drive from the Disney Property.
Feel free to ask any other questions and good luck with your planning.
