Well the Santander to Plymouth is around 20 hours so I can't see the Bilbao-Portsmouth being 15, probably wrong though. 
Either way it will be going through the Bay of Biscay, so get her to have a look and see if she can see any Whales/Dolphins as apparently it's quite common.
EDIT: Apparently the Bilbao-Portsmouth trip is supposed to take up to 29 hours if she's on that one http://www.eurodrive.co.uk/portsmouth_bilbao.htm
Now darkness had started to fall we can see the nice lightning caused by the agitation of all the ash particle.
