We’ve just crossed from Dover to Calais using the Irish Ferries ship Isle of Inishmore. P&O and DFDS eat your heart out, this is a quality ship. Proper fixtures and fittings; windows that don’t sound like they are about to fall out; huge enclosed observation decks at the back; a couple of decks with cabins. We didn’t use the restaurant or see the prices but it looked good. All in all a nice hour and half experience on a proper ship (or boat). Passports stamped and Covid pass checked by the French at Dover.
