I just booked the GV on The Dawn for Dec. 16-23, 2012. The price (for 5 of us) is approx. $2800 each which is what I paid for a Grand suite on RCCL's "Oasis of the Seas" cruise ship last year. Pricing will depend greatly on the time of year you book your cruise. Pass. 1&2 will be paying approx. $6,000 or so and 3, 4 & 5 will be paying $299.
The cruise total is approx. $14,000 ... if you take this number and divide it by 5 people so everyone is paying the same price ... the GV is affordable for the average person.
I can't wait to get on it and see this incredible villa!
