As you say, the events WFW already programme can get a full house in the biggest venue they've got.

And have you tried finding accommodation in Whitby during Folk Week? It's full, even when Folk Week doesn't coincide with the Regatta. Though new accommodation is being built in Whitby, there is increased residential demand too, from the off-shore energy and potash mining industries.

Whitby Folk Week offers a unique opportunity to participate. I'd start worrying when people stop flocking to the morning programme of workshops.
