We used Mutlu/Pegasus, I booked it to share with another CBF couple were booked on our flight. Mutlu asked for their names, which I supplied. Imagine my devastation when we arrived outside Dalaman and there was a board being held up with their names on it, no mention of me at all!!

After extremely mild confusion we were taken to the minibus and told they would swap vehicles at their Dalaman depot. We went from minibus to a Fiat Doblo type of car - I assume because we were 4 people and could fiit in a Doblo type car and a 7 seat minibus could stay at the airport for a larger party. Who knows.
Anyway, it was no great event, we were driven to the Pegasus place near the airport, moved us and luggage into the smaller vehicle and we were on our way in no time.
On the way back we were travelling alone as the couple we shared with are staying around 6 months longer than us. Driver on time, a little early perhaps, and two of us in a lovely minibus with leather seating (and not rows, facing seats - all very stylish indeed.
Happy
