I know one day I will probably have to. My oldest is headed to college in just a few months and I'm sure my youngest will in her time. My spouse hasn't traveled with us in 10 years as he likes to do his own thing. I love traveling with my girls but I also love to cruise so I know I'll be all right.
ETA: And as much as I like the look of the NCL Studio rooms (and I know
@Dug720 doesn't) I can never find them at a good price. For example, for a five night sailing in two weeks the price breakdown is: Studio-$699, Inside-$518, Oceanview-$698, Balcony-$599, Spa-$1798, Mini-Suite-$824, Haven-$3298. Obviously, that is based on availability but it kind of cracks me up.
