£65pp is outrageous!
it definitely used to be free to diamonds. I once took my whole family and spent a couple of hours.
Whilst the spa area is nice, it’s not £65pp nice - not even close (in my opinion.) And, of course, the exec lounge has never done a good selection of drinks.
What a shame. I wonder if there’s a market prepared to pay this? I cannot imagine taking a group of six (for example) again with this cost.
