We went on the British Isles Discovery cruise late August, early September.
The Marco Polo is not a modern ship, but all the same very comfortable in our Superior Twin Inside cabin. Shower and toilet facilities very small, but always hot water. Our cabin maid did an excellent job.
A good choice of food in the restaurant and bistro.
All ports of call ok with my favourites being Hon Fleur and The Scilly Isles.
Embarkation and disembarkation ran smoothly.
We hopped on the tourist bus and saw Dublin that way and stopped for a Guinness of course
It rained most of the time we were there, which took some of the pleasure away from the excursion
