Yes, we've used them and the service was EXCELLENT. Our driver was friendly and punctual, and the car was clean and very, very nice. We will definitely use them again. They are censored here, but get great reviews and recommendations on other disney planning sites.
Murray Hill is not one of the banned companies.
Thanks--wasn't sure so I didn't want to s-p-e-l-l-i-t-o-u-t Oh well--guess that is not who the OP was asking about but we have had a great experience with them and highly recommend.
