There could be several ways, the best approach would of course depend on the considerations that apply in the specific environment – so I’m subscribing to see the other suggestions coming from the community.

One option I’m looking at, for a similar use-case, is to schedule an email with the built-in DataMiner “Scheduler” and the “Reports & Dashboard” modules: scheduling twice a day, in your case, could be easier with a morning and an evening task that both run once a day
(or you just configure one email to be “Repeated every X min” 🙂 )

The report template can be configured to export Tables in CSV:

This is where you’d need to check what’s viable to embed your bookings data too.
Is this via SRM? Tables seem to be natively supported.

Then, the templated report you attach may have to be defined in a custom way (I seem to recall there was a Reporter API reference guide once, but I’m adding a separate Dojo Post as I need to find a way to embed customized building blocks in my reports too
https://community.dataminer.services/question/exporting-specific-alarm-console-columns-into-a-report-for-history-tracking-reporter-api/ ): Dashboard seem also to be an option here – but CSV attachments seem to be easily managed via the Report “Advanced Options”>

By default, you get some components that act as basic building blocks for a template – more specific behaviour can need an ad-hoc custom reports – but worth exploring if a “Bookings” component can help with your use case:

Another complete different option, could be to “offload” the required info into a .CSV file, locally on the drive, and then get it transferred with any application that can fetch data from the specified path – this seems designed for a different purpose, but sharing just in case you happen to have all the data available in parameter snapshot (e.g. booking data for a given VF in SRM):
