I had used a voucher for the venue again via treatwell, even though I had been there the day before - the receptionist could not find me in their system and the lady who signed me in the day before said I should pay the full £40 to them even though I had paid via treatwell - but I had the slip saying I paid - I did not find them very friendly - but the sunbeds are good but you can not change the music or volume - I would not pay £40 for 20 mins on a sunbed - way too expensive
