Hello, I will be leaving Rotterdam to Amsterdam on a cruise excursion where they will drop us off for 4.5 hours. With such limited time, I am planning to visit Anne Frank's house and the Church in the attic. I have received directions between the two attractions from Ms. Cecile. Now I need to get a starting point from where the cruise line bus( not train) will disembark. In his way I can maximize my time and plan ahead. Thanks for the feedback, as I am awaiting to buy my tickets in advance for AF house but need to know if this doable in 4.5 hours. Sam.
