There is a mousesavers code that is $55/night during your dates. That would total $330 for your room not including tax. Tickets - depending on what you get, would run you $297.86 each for adult Ultimate PHPs and $265 for a child - including tax. So, priced separately, you're looking at around $1224 including 10% tax for hotel (guestimating).
Now if you get Disney Club discounts at the current rate for 6 day park hopper plus passes instead, your total for tickets would be $278.81 per adult and $235.34 for a child coming to $792.96. Plus $363 for room = $1156. And if you went with 5-day passes, it would be cheaper still - depends on your arrival and departure times which tickets you'd want to buy. Of course this price would go up with the increase as of Sunday, so you'd have to take that into account unless you could book it right away.
Either way it seems you could save a little money if you booked it all separately and used one of the CK_ codes.
