I don't soak any of my snakes on a regular basis. I did have to soak my BP after his first shed with me - it was in pieces. If she wants to soak she will in her water dish, but with a MBK - not necessary. Especially with the humidity you're having she should have no problem with a perfect shed. Out of my 7 snakes I've only seen one soak and that was my Cal King right after she ate she soaked for a bit.
