Drop off and pick up process was quick and easy, both members of staff very polite and professional. However the buses were a nightmare, one bus dropping off and picking up people from all terminals which was already rammed at the parking. This meant everyone having to get off the bus to let those at the back who wanted to get off out, then everyone had to again get back onto the bus at every terminal, while picking up return passengers. This could easily be fixed by having one bus for picking up passengers, and one for dropping off passengers. Both bus drivers were rude and abrupt. I would have to think hard about whether I use the service again.
