Again using my sample dates, I found round trip air on US Airway for $446.20. I think this includes taxes and government fees.
So "my" cost for the trip is $1736.66.
I just checked Expedia. Without tickets - because no matter what, unless there's a package special, I believe you're better off purchasing tickets from an authorized reseller like Maple Leaf or Ticketmania - air and hotel came to $1199.15
So if you could get your park tickets for less than $500 total, you'd be saving money AND be able to purchase exactly the features you want.
Heck, even using Disney's own site, and letting them add flights, I came up with $1716.26 for the two of you - AND that includes two six-day, expire-fourteen-days-from-first-use Park Hopper passes!
And of course if you don't absolutely have to stay at Caribbean Beach, you could always look into renting points from a DVC member. There's a message board for that right here on the DisBoards. At the 'typical' rate of $10 per point, you could stay in the Beach Club Villas for $120 per night, or $600 for the five nights.
Airfare $446.20
MYW passes $515.46
Magical Express from and to the airport, and internal Disney transportation: free
Total trip $1561.66
Or you could stay at Old Key West, again by renting points from a DVC owner, for $80 per night for a total of $400.
This drops your trip cost to $1361.66.
And if you can get to Newark (Continental) or LaGuardia (Song/Delta), your airfare can be as low as $351.20 - so Delta/OKW on rented points/MYW six-day expiring Hopper now comes to $1266.66.

travel agent. I just did this pricing research for fun (yes, fun!), and resort/air prices are based on travel dates 12/3 and 12/8. YMMV.
