There is the ayre court hotel which is a 30 second walk from the club:
2, Queen St,
Seaton,
Devon
EX12 2NY
Tel: 01297 21455
Or there is the holiday park where you can rent a budget challet nice and cheap and that is only a 5 min walk from the club:
Lyme Bay Holiday Village
87, Harbour Rd, Seaton, Devon EX12 2NE
Tel: 01297 626800
Only thing I would say is that dont expect a whole lot on offer for the day after apart from walking along the beach of visiting the co-op as Seaton isn't exactly a hub of excitement in the day! ha ha
