My family has also owned there since 1985. Must have been a big sales year for them!
We've always loved it, and had stayed there every single year for our visit to WDW until the second week of our stay last year, when we stayed at Wilderness Lodge.
They've grown in amazing ways since 1985 over there at OLCC. The golf is awesome (I prefer the older courses, actually). They've added pools, condos, LARGE hot tubs, etc. There's a "beach" out behind the main clubhouse with a lake, where you can waterski, jet ski, tube, you name it. On site pizza place with late delivery, general store, restaurant, POOL BAR (he he), small theatre, movie rentals, arcade, raquetball, a LOT of tennis courts, PRO mini-golf course (used for the national Championships), pool shop with some pretty sweet swim gear, and by the pool on selected nights, LIVE musical entertainment.
You name it, and they've pretty much covered it. I've always loved it there, and I WILL be back in the future.
Have an AWESOME time!
