FWIW, I compared the prices for my Voyager cruise on CC and pulled my invoice out with a member of this board today for the same cruise in 2007.
By the time we added the Fuel Surchage into the fare, it was within about $300. per person more for a 10 night cruise. How terrible was that for an increase?
Perhaps some of the itineraries went up more than others, but, everything is up, gas, food, shelter, insurance, labor.
In 2001 my Alaska cruise on the brand new Mariner was $2400 per person. Who'd heard of Radisson back then? Few of us. 5 years later, and 3 days shorter it's about $1600 more. 5 years ago, my house was worth 1/3 of it's current value.
