Took my parents of Carnival Triumph for their 45th Anniversary, they had the time of their lives!! (and have cruised 3 times since then, in 18 month, so Iguess we started something!!)
Didn't think they would, but they participated in nearly everything. Even were chosen to go on stage as the "married a long time" couple (with newlywed and 20 yrs couple) during one of the "shows".
Quite something to see my 65 year old father as a "Carnival Chippingdale" during the "Full Monty" skit! (Yes, including the dark shades, boetie and SPANDEX underpants...nothing else!!) And my mother exclaiming "I'll kill him!!"
