Apologies if I'm trying to second guess what
@RELL6L was thinking but that it was the "going somewhere and home again" that might have suggested a once a day type thing?
I was thinking that it might be a mix of longer routes running in to undertake/augment a number of services. However, there's only a limited amount that you can glean from the registrations and so I'm happy to wait and see what actually is planned. Very interesting days ahead as these teaser graphics, route registrations, repaints, and other information already shared give way to the detail of what is going to be on offer.
Aside from the Exmoor Coaster, I'd be surprised if anything else would feature in Minehead but happy to be proved wrong
