Trying out new yoga instructors

So once again my Mon/Wed morning yoga classes are looking for a new instructor.
We had Sally today. She was pretty good. Though sometimes she wouldn’t tell us what we should be doing.
Next week Sarah. And the week after that someone else.
I have only been going to morning yoga once a week lately because Wednesdays I like to attend advanced body conditioning in the evening.
So hopefully we will find a good replacement for the morning classes. One of my yoga friends suggested the reason many people don’t attend is because of the time. She thinks if we had class at 6:15 more people would come because many have to be at work at 8. There is no way I can get out of bed at 5:15. I mean, I can barely get out of bed at 6:15–and it is just going to get harder as it gets colder and darker.
