Cheap exotic spa in England?

I went to Nirvana spa...WOW..what a fabulous place!!! What a FAB weekend away!! The spa offers 7 different pools, all different types. The floatation pool is simply the best...so relaxing...and they offer many different types of treatments while you're there! It was �79 for the evening session, full access to the entire place with the flotation pool. I bought an additional treatment while I was there. Drinks are all free. I can't wait to go there again! it's in the Reading area. I stayed nearby at Madejski Stadium hotel (very new, very inexpensive, very quiet!!) which was very close to the spa! Worth a look at!
