I'm the OP!!
I just wanted to update the thread with my information.
I asked the question about walking because I wondered if I needed to walk my May reservation. I did not want to have to do it, but I would if it needed to be done.
I decided NOT to walk it for reasons of convenience really (and the risk of having my ressie messed up with changes) I firmly believe in trying to make as few changes as possible to a ressie .
This morning, I called MS and booked the first 7 days of my May BCV studio vacation, WITHOUT walking!!!
I'll call tomorrow and the next day to extend the ressie, but I will leave my walking shoes at home for this reservation.
Now, if I was looking at a high-demand time with an all or nothing resort request, I would reluctantly walk, but not too much, just the few days before if I had to.
