I do agree with you, however HAL are sadly lacking in communication skills.
We are sailing on Rotterdam on August 28th and have known for several weeks about the changes taking place. Only today have the Ports updated their websites, but as yet no word from HAL. I have pre cruise hotel bookings in both Amsterdam and Rotterdam, but will not cancel until HAL confirms the embarkation port.
Giving them the benefit of the doubt about planning being beyond their control, I would expect to hear from them by tomorrow morning. 🤞
