Congratulations, Isabelle!
Once the drains were out having the BA and SRS at the same time wasn't such a big deal. I tended to do my breast massage routine in the shower room because of the nice hard walls, towels immediately handy for cushioning things, and the AC wasn't blowing on my naked butt when I did it.
You may find it handy to create a paper towel shroud with tape and tuck it in where the control panel snaps down onto the AC unit above the bathroom door. That can reroute air flow if the direct air flow on you is too chilly. If not, then no need.
Welcome to the club! Next time you see Som tell her Cara Ramsey says hello.
