Welcome, OP. Great question by the you!

Blackpool is good, but I prefer Skegness.

In all honesty, I couldn't nail down a single favourite place. I have a list of places I'm desperate to return to, which is probably the highest accolade from somewhere obsessed about going to new places - places like Japan, Yunnan Province, the Isles of Scilly, Kerala, the Northumberland Coast, San Sebastian, Bukhara...

Sorry.
