There is an abundance of cruise ships sheduled for May, only a handfull of days without one

Next will be the MSC Poesia and the Deutschland on Thursday May3rd, both PoC's followed by the Braemar again on Saturday, TR, and the Ryndam on Sunday also a TR.
There will be three in on Tuesday the 8th, Braemar TR again, obviously out on a three day cruise, Emerald Princess and Princess Daphne both PoC's, so lots of cruise activity at Western docks coming up. It seems cruising is as popular as ever despite recent mishaps although there are a few who are now quite wary. I also heard, as PaulB says above, that some passengers at Dover very recently, decided not to brave the elements at the very last minute.
