My advice to
miamihoosier is to request a full refund of MP miles, link OP and MP accounts, transfer the miles, and then re-book the family vacation on continental.com with OP miles.
Any reservation made with MP is going to be a gigantic pain next year once the MP reservation system ceases to exist for new bookings, since it is pretty apparent that OP's system will be used going forward. (Plus the OP website is just plain better to use.)
We'll leave out of the discussion that ORD-RSW is a trip FTers would take as a revenue flight and 100k should be spent on a J class TATL award.
