I'm guessing you are renting points? I'd price out BLT. Pool isn't as nice, sure. Maybe that's not the main consideration for January. But being RIGHT ON MK for a once in a lifetimes kind of trip like this is special, and BLT's chart is low enough it might be competitive.
The BLT theme park view is on my bucket list, and you'd only need one of your rooms to be in that category. Standard view is competitive in points and difficult to book. Kidani/SSR should be easy to book, even in a couple months.
