Not free any hours. Also requires booking, which is a good thing to do day before you intend to use the spa, it was rather booked and busy the days we spent at Westminster.
Sorry, as I was resident it was all included, my partner arranged for me to have access anything. Give them a call, they are most helpful.
Sorry once again.
The spa is not free. We asked at reception if we as guests got free access but were told we had to pay.
