2 nights each if you don't really unpack yes it will be painless.
Bell Services will take care care of moving your luggage if you want ( it might not get to your room until that night) and then all you need to do is stop by the front desk sometime during the day to get your room Keys. (early morning 1 person could do that if going to MK that day all the more easier)
We will be doing a split stay this next trip and may try to do 3 resorts over 13 days and 4th of July.
