Spa days - recommendations?

Hi everyone!
I was hoping to go for a pamper day at a spa for my birthday - we usually go to Hoar Cross but although my birthday is still quite in the future, the treatments for the day & days surrounding it are fully booked and it's a very expensive day out to just have a meal and a swim in the pool.
I've always gone there before, but could anyone recommend any lovely day spas that aren't a million miles away from me? We're in Shropshire but could only travel about 2 hours max due to animal commitments in the evening! Alternatively nice hotels with spas? Thank you x
