What "more information" are you wanting ?
On the folkweek website, click on "browse by activity" to get a dropdown menu for ceilidhs in town, latenight extras at Salcombe, and workshops. These give locations, start times and ticket prices. Advance tickets are available from Sidmouth tourist information,see

The D4D social dance series organised by Roy Godswen has stayed aloof from the rest of the folkweek. It isnt participating in the supporters discount scheme, and if I remember rightly was aiming to sell a maximum of 300 of its own series tickets and not get involved with tickets on the door for individual events. They don't seem to be keen on publicising their events to outsiders, so presumably have achieved their target ticket sales.
