You're right mandimoo. I went to an overnight spa and there wasn't a chocolate bar in sight!
Was all low fat food and was pretty boring.
Also not much to do at night, as no entertainment.
In end we drove to nearest town, found an off licence and brought wine chocolate and crisps and sat in our room munching them while watching tv.
Otherwise if jsut a day trip just take swim costume, bath rode and slippers or flip flops.
They also have classes and gyms, so could take gym kit.
Where I go at Ragdale you have to put deposit down on dressing gown and also pay a tenner for the use.
If pre-book they send you a brochure and leaflets explaining whats best to take, and when I get to mine always ask if been beforem, as if not they'll give you a tour.
They're very helpful and you'll ahve a lovely day!
