Hi Jo Anne!
Most probably, that service was not provided by Aerocity, because you paid directly to Hotel instead to the driver, and the price does not match our fare for that trip-ours would be less expensive.
Some hotels do have their own legal minibus service to the airport. Some of them charge for the ride and others offer it as a complimentary service.
Nevertheless, I suggest to book the service in advance, in order to avoid the risk of boarding a non-licensed vehicle which could lead to unexpected problems.
Be aware of some "pirate" vehicles operating without control at the airport, lacking any type of license and control.
We place at your disposal our web site www.aerocity.com and/or our toll free number 900 71 35 83 in order to make reservations in advance or from the airport in order to be sure about which vehicle to board.
Best regards.
Aerocity.
