Many years ago we won a "free" bingo cruise. It was from the buy raffle tickets to get a free cruise. What a cruise line considers free is not what I consider free. It wasn't at no cost as there was indeed a cost for us for this free cruise. Port fees, taxes and a non-commissionable charge all meant we won a discount on a cruise. Add in the charge to upgrade from the inside cabin and while we had a lovely cruise, it was hardly free.
You gotta pay attention to ship talk and accept that sometimes, things have a different meaning on a ship than on land.
Ironically, I just realized we have stopped playing bingo and purchasing those raffle tickets ever since. 😀
