I always enjoyed Rotterdam's Watertaxi - that is, until they stranded my friend and me at stop number 75. If the Watertaxi drivers/captains are going to refuse to stop at dock #75, then they should take it off of their list of stops.
You will be able to ride a watertaxi to stop #75, but no matter how many times you call to request a pickup at stop 75, or call to ask where the promised taxi is, you will get no answer other than "it is on it's way".
Very frustrating when you see watertaxi after watertaxi zoom by stop #75 and no driver/captain willing to pick you up.
In the central area, it is a great/fun service. DO NOT RELY on it for stops far from the center.
