I've just returned from my Croatian Island Explorer.
After talking with Addison Lee, I changed the pick up time to 7:00am. The driver was there right away and took me to Heathrow from Birmingham in a very fast time.
The return journey was not so good. As I was at the back of the plane, went through a long customs, and was last to get my luggage from the carousel, the driver was not there at the collection point. He had sent a message, and was waiting in the car park.
It was a longer journey than before due to the traffic. When I was home, he wasn't very subtle in waiting for a tip!
