Hi....Villas at Polo Park are brand new and just south of 192 on Hwy 27......about 10 minutes to Disney........nice units, nice pool, must drive to any restaurant as they are out on 27 away from the resaurants by about 3 miles........Blue Tree is an older time share in a GREAT location at Lake buena Vista...just outside east entrance to Disney with lots of restaurants including fast food just a short distance...Blue Tree is older but IF you get a two bedroom for 60 or so a night it is a good deal....any more than that and there are better deals right now.....Celebration is a brand new timeshare still under construction.....they pop up on alot of auction sites as they are trying to get people in to see the units......They are just out side Disney about 7 to 10 minutes to the parks.........If they are all about the same price, I would go with Celebration for brand new and location.....none of these is a bad deal in my opinion if the price is right......if Polo is lot less expensive go for it...I am sure it is cheaper only because it is out a ways on 27.....Ted
