Taxi drivers will try steal passengers from the airport bus services with excuses like "I know a quicker route to your hotel" and all that.....they tried doing it to be before when I was in Marbella.....I had booked my appartment and had the bus waiting for most of the people on our flight....next door is around 7 cab drivers who all rush up trying to get us to go with them. They don't know any qucker routes to your hotel....as they'll probs take the same route...get stuck in the same traffic etc.....
