Having arrived in plenty of time for a transfer we were left waiting at the bus along with another family, long enough for another mini bus for that car park to return from the airport. Once our luggage was loaded, instead of going to the airport, we were driven to another, more distant car park, to uplift other passengers. The driver waited at the other car park until the bus was full during which time another much larger bus arrived to service that car park. From arriving at the first car park the transfer took in total 45 minutes. If we hadn't allowed excess time we would have been in danger of missing our flight. Having used this and 3 other transfer services before we were astonished at the poor service.
