Last week we planned a summer holiday, which started with getting the overnight Hull - Rotterdam ferry. Family of 4 + vehicle.
We left it a couple of days and went to book annual leave x 2, Cattery etc.
Went back to confirm yesterday and the ferry price had more than doubled. The increase was over £900, taking it to £1700 return. Not a glitch on the booking system, P&O say it’s dynamic pricing.
We are have now booked ferries to/from a different port, several hours further away.
If you are planning to use a North Sea ferry this summer, it may be worth booking it asap.
