I had trouble with most of the calendar based sign-out tools since everything was by period and not by a specific time.

I wound up purchasing, and find it incredibly easy to use.    

1. Easy to use
2. Uses period instead of times
3. Web-based, hosted externally
4. No login required

1. Expensive $199/yr ~ it is designed for EDU so that is the schools cost.
2. Doesn't snyc with GAFE so users need to be manually imported.
3. No login required.   I have not run into any issues yet, but technically malicious teachers or students could signup for others or delete others labs.   However it does keep a log which I think could show if someone had it and then was deleted.

Hello School IT:

For those of you who manage flexible computer lab or other tech resource scheduling in your elementary school (and find it successful) what is your model, parameters, limitations, etc. for this?  

Thank you in advance!
