My family of 4 travelled with 2 other adults - we all wanted to stay together so we decided to stay at Disney's Old Key West. It was great! The bedrooms are huge, bathrooms are great, we had a full kitchen and couldn't have asked for more. We also had a washer and dryer, which we didn't need, but was nice in case we did. I do have to say though that the sofa and loveseat seemed to be a bit dated. Other than that, the room was nice.
We stayed in building 22 which was a bit of a walk from the front desk area, but really wasn't a big deal as there was a bus stop pretty much outside of our building.
We have stayed at Port Orleans-French Quarter before as well as one of the value hotels and this was our favorite. It was a very quiet hotel so if you are looking for a place that is much livelier, this is not going to meet your needs. If you have a car, parking is great as each building has its own area to park. I didn't realize how big this hotel was - it can be confusing if you are walking around.
