SEJ,
We stayed at Vistana Resort as a trade on my parent's timeshare in March 2000. The location was great and the units were very nice. If you do a search of "Vistana" on these boards, you will come up with plenty of info especially concerning what area to expect based on your check-in day. Our first night was a rental and since it was Friday we had the newer Cascades section. On Saturday, we checked out of our rental and into our RCI exchange week and were moved to an older unit which although suited our needs just fine was not as updated as the first unit. However, this did not affect our overall opinion of the resort. I would recommend it. We are trying the Vistana Villages this December. Although it is a little farther away, it is less per night (we are renting) and is a new development. Have a great time!!
