I've never booked through them before, but we have stayed and are staying again in June at Regal Palms Resort which is adjacent to Highlands Reserve.
The location is about 20 minutes from Disney. I don't know if you are familiar with the area, but you would go to the end of 192 where it turns into route 27. It is probably about 3 miles further down on the right. Depending on when you go, it can be a lot of traffic to get to the parks.
The houses look nice there, but if you want to be closer to the parks, I think I would suggest Emerald Island, Windsor Hills, Windsor Palms or Terra Verde. You can see homes at all of these places at
www.villadirect.com.
My one suggestion in renting a home or condo would be to book directly with an owner as opposed to a managment company. The rates will probably be less and you will get better service. Most owners want to really please their renters and will make sure that things go right for you. A management company won't care once they have your money. I've heard stories of where people go to check in and the houses are filthy or the pool heat they were promised was never turned on. Things like that.
Some other places to check for private owners would be
www.cyberrentals.com and
www.vrbo.com. We have used these sites for several rentals over the years all over the place and have never ever had a problem with any owners.
I hope this info is helpful to you.
