Just got off the Ventura on Sat 29/03/2023.
Question 1. Very poor selection and not a lot to choose from on the cheaper list . Dearer one, not much better.
Question 2. No need to book.
Question 3. Internet Package not worth the money.
Question 4. Terrible , Food tasteless with little choice. short of staff , hence long queues and long waits for drinks.
Like you my last PO Cruise was in 2013 and I said then never again.but I give them another go last week and this time I mean it . Never Never P&O AGAIN
