Extra Sunday buses to Cribbs for Xmas?

First have today registered a new temporary route, the CC, to run between Weston-super-Mare and Cribbs Causeway on the four Sundays in the run up to Christmas:

It looks like it's a frequency boost for the X5, which has been running on Sundays for a couple of weeks now.

The fact it isn't registered as an X5 might mean it will by-pass Portishead and run from Clevedon direct along the M5 to Cribbs. As soon as First advise, we'll let you know.
