Fantasy is great. You will love it, the kids will love it. The product is wonderful, but yes it is expensive. We had the Wonder booked for this past March Break from the day it went on sale (about 17 months before the sail date). The choice of the Wonder over the Magic and Fantasy was so that we could do something else this summer if we wanted (and ended up booking a cheap 7 night on the Getaway). Most of the time I will take two trips over one.
We looked at March Break 2016 when it was released, but given the prices and that 3 of the 4 ships are doing short cruises (if the Fantasy is your first longer cruise you will notice the difference) decided to do something BIG in the summer of 2016 instead. Ended up booking Alaska on NCL under a kids sale free offer for $3,800 for all four of us in a balcony. Would I love to do DCL to AK? Of course, but balcony prices alone were twice what we paid. Difference will pay for a few days in Seattle before, plus air (out of Buffalo of course), plus pretty much all the excursions we are looking at. We are willing to pay a premium for DCL, just not that much of one.
