My mother swears by cruises, up and down. She's an addict. Loves them.
Me, I got sick on the Boblo Boat, going to Boblo Island up in Michigan. I've yet to try a cruise but, if she has her way, mother is dragging the children and I along on a trip down to Cozumel and such.
I think a lot depends on the cruises. I mean, I've heard there are a lot that tend to be really dull, but I've heard about some interesting ones too. Just this winter, I spent a day making laurel wreaths and teaching my mum how to tie a toga for the toga party that they were supposed to be having on one of her cruises. She's gone snorkling and she's swam with dolphins and manatees. She loves shopping down in Mexico (and I always make her bring me back a bottle of Kaluha, which she can get for about $5.00 a fifth down there). I don't think she does many of the gambling cruises...she looks for the ones with a busy itinerary and several different ports that they dock at.
