Hi Jane
Sand Sculpture.... daft question but is it happening on the beach? Might go myself if it is
I've copied a link to laterooms which might help. I don't live close enough to recommend any sorry. I usually check out the hotel's own website before booking with laterooms as you can sometimes get a better deal. Or you could message some of the Blackpool members they might be able to help as not everyone reads the forums.
