Best sexy romantic hotels with Hot tub?!

Me and my fiance hardly get time alone because we live with my parents who work at home.. its tough so for Valentines day were looking to spend a lovely weekend or possibly 1 night away together, my ideal hotel would be gorgeous room but not fussy, but i really want a hot tub on the balcony outside but private?
Somewhere close in the UK too Wales ?
Thankyou x
