Dilemma?

Alright, so I'm in a rather interesting dilemma in which I would like some feedback. I'm graduating soon, and my folks feel bad that they haven't contributed financially to my education. I've never been worried about it or asked, but they would like to treat me to a nice graduation gift of either a cruise or a down payment on a Harley Davidson. Either way, lucky me! I have never been on a cruise but have always talked about wanting to do one before my time ends. Definitely a bucket list item, however I started riding motorcycles about 7 years ago and absolutely love it. I have a crotch rocket but am ready to put the kiddy bike away and get a man bike like a Hog or a V-Rod. What do you think?
