Blackpool Britannia Hotels.
I’ve done the Castle one many times, with no issues. Also the one near the North Pier.
I have never done a meet at the older one, on the Prom near the big roundabout at the North end of the town....
Know the place. It’s walk straight in, & the stairs are directly in front of the door, with a fairly large reception to your left.... Think a lift on the right. All the others, the receptions are set back, or tucked away. This one, it’s very prominent. Don’t fancy the “Hi, can I help you Sir”.
