Glad you arrived back in time, despite the taxi cost. We are boarding the Getaway in Southampton this coming Thursday on a similar itinerary and planning to do our own excursions. Having experienced a couple of significant delays on German ICE trains in the past we'll be extra careful. Really looking forward to the cruise - our first time on NCL/ Getaway.
Yes, Bilbao is a difficult train journey from Le Havre (at least 12 hours and part by bus). If they had known they were going to be delayed it would have been much better staying the night in Paris and then heading to Bilbao the next day. But of course that is hind sight!
Also cannot have been easy finding accommodation at 10PM at night in Le Havre.
