We loved being back on a small ship without crowds and queues.
The only significant negative are the ship organised excursions. Most of these were sold out months before the departure date. I also discovered, by accident, how much the company add to the actual cost of at least some of the trips. It's scandalous.
We tried the Panoramic Donegal' coach trip adverted struggling to find a way to see the area otherwise. After being herded on to full size coaches we were driven to a pub to experience some local flavour. After a bit over an hour we were driven back to port. Sadly there was little opportunity to see anything 'panoramic' as the coach was restricted as to which route it could take. The guide was genial but lacking in any specific knowledge. If this is an indicator then I would avoid ship excursions.
