I used Stena ( Celtic ) for the first time this year home from Cherbourg and would like to warn anybody thinking of leaving their dog in the van ,they only allow 2 visits to the dog one at 7pm and the other at 7am (a nice time to get up at on your holiday ) for walks etc , if you get a kennel there is unlimited access but only 8 kennels ,Irish Ferries had over 30 and plenty of access to the deck with the kennels. On the up side the singing act in the bar were excellent and are booked all season
