dannysgirl, you should totally do it! if you do a little searching, there are so many great deals to be had on cruises. I went on a 7 day cruise with 3 port stops and it was $499 plus fees, so it ended up being about $580 per person. everything is included except gratuity and shore excursions
five of my friends went on a 5 day cruise in december for $189 per person!
