RHLS LAB hours consumption

Doing the RH403 Satellite course, I have already spent at least 4 1/2 in one chapter, I am hoping that this is really at max 5 hours, not per host (7 hosts *5) 35 hours?!
Reason is that, it takes a long time to bring up the VM and shut them down, so I usually start them as soon as I hit reading, it 'd be good if the lab hours are part of the progress report especially when one need to redo the lab at least a couple of times before an exam.
