Hi - We stayed at Orange Lake last November and thought it was incredible. We got it thru SkyAuction for around $200 for the week! What a steal!!
The unit we were in was brand spanking new and looked just like the pictures on the website. It was clean, large, bright, airy and even nicer than my house which is only a few years old!
The only downside was that we did have to drive to the main pool area. Didn't bother us too much since we were also visiting the parks. So on the days we went to the pool, we were there for the long haul.
It was a very easy commute to Disney and had a Publix pretty much right outside the back gate.
Never stayed at Vistana Resort, just the Villages which we also liked. That was a much smaller resort with a beautiful pool. (No slide though).
I think you would be happy at either. But I understand your concern, I'm trying to pick between two resorts (CPGV and Horizons) myself.
I know when I plan a Disney trip, I want everything to go great because it is an expensive trip no matter how you slice it. Plus it is so nice to get a way and stay in a beautiful resort. I never want to be disappointed. I think Orlando's resorts have spoiled me!!!
Happy planning!
