We used them for our last trip and I would use them again if we weren't using ME.
The driver was waiting for us at the bottom of the escalator for baggage claim, with a sign that said "The Peterson Family". My children were delighted to think that they were getting special treatment! The driver told me and the girls to wait on the side, while he went with my husband to help him get the luggage. He was parked right outside of baggage claim, so we didn't have far to go with the luggage. Again, he was very helpful with it.
The cars were very clean, and didn't smell at all. I have a problem with smells and car rides, so that is important to me. I tend to get car sick with overwhelming scents. We stopped at a grocery store (not sure which one) on the way to Disney. There appeared to be several of us shopping for our stay.
When it was time to leave, they were very prompt. We didn't have any problems. I would definitely use them again. Until we got
free dining, I was considering it, just for the grocery stop. Once we got FD, we decided to forego the grocery stop and just put a few snacks in our luggage.
