We're just off the Regal Princess after sailing 12 days around the British Isles. Servers were far understaffed in all areas we visited. Horizon Court was good for first 2 days and the last day but all days in between it was self-service for beverages and clearing tables at the times we ate. Very disappointing service when ordering drinks in bar, Piazza, Princess Live! and a few other venues.
This was only our second cruise, the first being in 2017 on RCL Mariner of the Seas which was an excellent experience.
