Is there a dashboard/overview type page for OR? I'd like it ideally to show arrivals, stayovers, departures, the inbox, tasks, and guest items waiting on (payment, signature, etc)
Kind of. There is a Daily Checklist report that includes much of this information.
Where do you find the daily checklist? I searched for it in the help section and couldn't find any info on where to find this, as I'd be interested in this as well. I'd suggest putting this info below the fold on the bookings page. If you use a big screen, as I do, there is a large amount of blank real estate that could be used as an ideal dashboard to visualize your schedule and tasks of your team.
It's under Reports - the very topmost one, in fact. :-)
