I've been on two short p&o cruises on smallish ships, both child free. I'd totally go again.
We had very basic cabins, no window, reasoning we would only be heading back to sleep so why pay for more!
Generally avoided buffets, just in case.
Really liked the freedom dining choice when you could go to dinner when you wanted and not be sat with the same people. Pleased with the food.
Only did a few excursions - pricey and basically coach trips. I preferred the stops where you could just get off and walk about.
Hugely impressed by the entertainment. Mega professionals, doing several shows in a week in repertoire. Also you'd see them doing singing duos, playing piano, solo singing on other nights.
There was lots to do; library, beauty salon, gym, cinema, lectures, exercise classes, dancing class, jewellery demos.
And if you like lounging quietly with a cappuccino or a cocktail and a book, which I DO, lots of places to relax.
Several swimming pools, I preferred the little one that few people seemed to discover.
I loved the dressing up black tie nights!
One of the shops had a glamorous foyer with resident harpist.
I want to go again now ...
