we have sailed many times, generally split between Princess, RCL, Holland America, Norweigian and Carnival.....mostly Princess and RCL...about 22 Cruises
Last August we took the 12 day UK, cruise out of Southampton, to Ireland, Scotland, Orkney Islands, Guernsey Island and Le Havre.
We noticed lack of Purell Hand Sanitizing stations, instead they had double sinks in the LIDO but nobody was using them.....there were a lot of sick people with the Australian Flu, they sent around a notice warning us to wash our hands and avoid the public washrooms.
