This was our second cruise on Eclipse following a Med cruise last September, and if anything the standards of service and overall cruise quality were higher, not by much because it would be hard to improve on the Eclipse cruise experience, but just enough to notice.
The standard of cleanliness in the public areas was excellent; maybe it was influenced by the small Noro outbreak on the previous cruise and housekeeping's desire to ensure it did not return, whatever the reason the ship was spotless.
Even the entertainment, where I have in the past felt Celebrity were inferior to P&O, seemed to have improved; although they are still a bit stingy in only having 3 production shows over a 14 night cruise, but this was compensated for by the theme nights which were very entertaining.
Accessible balcony cabins on Eclipse are spacious and well equipped, but they do need extra drawer storage.
