Another option is to head over to MGM and hop a bus to the Contemporary or one of the other MK resorts that are on the monrail. Once you are there, you can check out the resort and then hop the monorail to the next resort.
We did take the monorail once to the TTC and then headed to MK that way. The trip took much longer than we had expected. Now we head directly to either the MK and then head over or we go to MGM and do it that way.
I would probably take the MK bus to MK, walk over to the CR (it is a VERY SHORT stroll from the bus stops and then start my exploration from there.
The cool thing about your plan is that you have so many ways to do this. it all depends on your timeline. Also plan on how you are going to get back to the BC. Take into account the time of day. The easiest way back would be a bus from the MK to the BC.
Have fun!
