If a large enough group books in advance, isn't there a discount that the cruise line provides??
And, would your wife book the whole package (air fare, ground transportation, etc), or just the cruise and leave everything else up to the individual??? I'd love to go and get away... but, being under 21, they won't let you on a cruise ship by yourself... however, I know my mom would love to get away...
Earn some brownie points with her! :thumbs:
