Like how constable145 found out about Rhapsody getting put up for buyers, on Boats.com, Grandeur of the Seas has also been put up for sale for 300,000 USD. The title is listed as Cruise Ship 2400 Passengers -Stock No. S2388.
Since two vision class ships were launched in 1996 that look similar, (ie the Enchantment) I took into account the passenger counts of both ships (remember Enchantment was lengthened in 2004, which increased the passenger count to 2,730 passengers. We can also most likely rule out Enchantment as the price to lengthen the ship was so much that I would assume that they would prefer to keep the ship sailing under Royal's colours for a little while longer.
