We stayed at Orbit One a couple of years ago and it was ok, but not our favorite. We were first placed in a unit that was not updated and in pretty bad shape. We immediately declined this unit and agreed to wait 3 hours for one that was updated. It was much better. It's a simple resort, not very large, not many activities, but it's a great location to WDW property. Our unit was large and had everything we needed. I have since heard that all the units are updated, but this would be my main warning. My parents stayed with us and they thought the unit was just great. They don't trade timeshares like us and we've seen so many our expectations are pretty high sometimes. Have fun.
