Get a quote from buycruises.com before you book. We just booked our second cruise from them, this time on the Diamond. $48.00 Higher than the other quote we had, but we trust them and thought it was it worth the difference.

I looked on their website and then called my travel agent. We are going 03/19/04 on the Diamond from San Juan for 5 nights/6days 2 for 1 fare. My travel agent obtained the price of $1,747 pp for balcony on deck 9 including port charges. Includes tips, wine and bar set up in your stateroom.
