Simple booking form/calendar?

Are there any modules or snippets in modx that are usful for a guest house/hotel booking system.

I just need a simple reservation enquirey form (eform?) and a calendar that will show availability.

Anyone? I would have thought someone had done a site for a B&B, guesthouse, hotel or something similar.

This holiday cottage to let uses a slightly modified version of CALx.
Should be in the repository somewhere
