"Cruising is fine for some but those boats stop at every T shirt, trinket & jewelry store on the SE coast."
Over the past several years, the DW and I have either taken the big silver bird or AMHS to several SE towns for a visit. One of the more enjoyable ways to spend a few hours in, say Ketchikan, is to get a good seat at a bar overlooking the cruise dock about 2:30 or so in the afternoon and watch the surge of folks trying to get a last-minute shot at trinkets before reboarding for a 5:00 cast-off. By the time of the 2nd or 3rd beverage (or is it 3d or 4th?) at about 4:30 / 4:45 interesting to see how the diehards deal with rushing to get back to the ship with their purchases before the cut-off for reboarding / departure.
I also think there would be quite a few segments of industry that could take lessons in effective demobilization from the trinket vendors in SE: within 3 minutes of the last cruise ship pax walking away, the shutters are down; by the time the ship casts off the hawsers, the trinket shop is closed up, the lights are off, and the staff is back at the hostel for the evening.
