Villa or condo for sure! We always try to get a one-bedroom condo when we go on vacation. We really want the privacy, for one. But, also, we eat breakfast in the condo or suite, so we save time and money, as well. I love breakfasts out, but I always thought that it was such a time waster when there is a lot one wants to do. Also, we're able to keep milk for the kids in the kitchen, etc.
I've never had a problem driving in Orlando, either. There are so many signs directing drivers to the correct parks, etc., it's pretty easy. It can get a little fast, when you aren't sure where you're going, but it's easier, because of the signs, than any other unfamiliar city.
Also, because of the competition out there, the condos /villas are all beautiful. And, better priced than the Disney hotels.
