We have cruised mostly with P&O and been on Oriana before. We thought she is very nice, following her refurb last year (although if our bathroom wasn't missed, they don't appear to have included cabin bathrooms in their refurbishment plan. Still got the dated & scratched pink suite and very dated shower curtain).
On-board entertainment, food & wait staff attitude (in Conservatory) have seriously deteriorated since our last experience on Oriana / P&O in 2015. Headliners were a let down this cruise - voices not enthusiasm and an old 'has been' (Roy Walker) was wheeled out again! The best bit was their guest speaker, Ian Brown but he unfortunately only had 3 spots.
Absolutely nothing to gain from grumbling but very disappointed that Captain would not allow tender disembarkation in Guernsey on penultimate day but we all watched Ventura guests leaving on their tenders! If Oriana tenders aren't up to the job (single hull apparently) P&O should reconsider St Peterport as part of her itinerary!
Aft, starboard, window facing semi circle deck 9 (overlooking pool on deck 8). Was wary of people walking past & being able to see in but tested (lights off & on) and net curtain adequately blocked their view. No issue with cabin position.
The dressing table could do with being 6" shorter for when bed is in queen layout - to avoid banging knees getting past. Fine when in twin layout though.
Plenty of wardrobe & drawer space.
