Spa at The Royal PDC ("SpaZul")
Well, this was a little disappointing to read today on tripadvisor. Not a deal-killer, but an FYI.
"previously guests were able to make use of the spa for the whirlpools, steam, sauna for free. Now the charge is $25.00 USD per person per day or you can pay $60.00 USD per person for the stay."
If you have a service, you can use the spa on the day you have the service at no extra charge.
