Southampton had to pull out all the stops - and ladies of a certain age who direct you around the terminals - in January when a record six ships were in port.
Now comes news that P&O Cruises is celebrating its 175th birthday on July 3 next year by bringing all seven ships to the port on the same day.
It will be the first time in history the entire fleet has been in Southampton on the same day.
"It will be quite a challenge," Doug Morrison, Southampton port director admitted in what must be the understatement of the year, given the port has just four passenger terminals.
A fifth one has been approved but it won't be ready until 2013.
Doug tells me they can moor two ships where that terminal will be - it's by a warehouse where they unload fruit - and another one beyond the Mayflower terminal. The problem is checking passengers in. Most likely, that will be done at a local hotel.
Some 15,000 passengers are expected to disembark P&O's seven ships when they arrive in Southampton on the morning of July 3, with another 15,000 embarking that afternoon.
Factor in hundreds of sightseers - it will be quite spectacular after all - and I'm guessing it won't be the best day to be on the road in Southampton.
All seven ships will then cruise out of the port in convoy, heading out on special anniversary voyages to destinations including the Canary Islands, the Mediterranean and Baltic.
The fleet line-up includes the 710-passenger Adonia, which joins P&O from sister company Princess Cruises in May after being named in Southampton by Dame Shirley Bassey, and Oriana, which is being transformed into an adult-only ship during a refit in November.
Among changes, they are replacing the kids' club with more cabins, adding a Ocean Grill, which will be serving dishes created by Marco Pierre White, and updating the spa.
Next year promises to be quite a year for Southampton as one month before the P&O event, Cunard will be celebrating when its three Queens meet in the port for the first time.
The Three Queens Event, on June 5, during the Queen's Diamond Jubilee weekend, is very timely given Cunard's royal connections - the Queen named Queen Elizabeth at a gala celebration in Southampton last October.
