Book two separate vacation packs - one at each resort.
Though DIsney makes it as easy as possible, it's not all it's cracked up to be unless you will never go to WDW again and simply MUST try two resorts.
All the packing/unpacking and stress of checking in again and wondering if all your stuff made the move with you, will you like the new room, etc. is more than the benefit of staying in two rooms for me.
Some will disagree, but once I unpack....I aint doing it again til I leave for the plane!
The WDW reservattions people will work it out for you, but it might actually affect your package if all the stuff you want is not available at one or the other resorts. Give them a call to be sure!
Good Luck!
