How do the mineral pools work? Do you need to have a reservation to use the different pools once you have paid admission? For instance you need a reservation to use the grotto? Or is it first come first serve? Also how much is the 2 person private caban

No. None of the minerals pool's need reservations. It's more like a first come basis. Most pools are large enough for more than two people. I believe the only pool that can hold 2 people is the sulfur pools. Your paid admission will give you access to the pools. The grotto is a separate addition and you will need a reservation for that one.

With covid they want to reserve you a date for entrance. Go online or call. Each pool such as mineral pool is first come. Cabanas are secluded. Call for those prices, I don't use them.

The mineral pools and mud are included along with your admissions. They do not need appts but there is a suggested time limit in the mineral baths as a courtesy to other guests. The grotto is a smaller area and needs assistance from the resort hosts to take you down to the subterranean level and then paint the guests with the moisture mask which is why that service needs an appropriate. The cabana and premium package are now priced at $390 and $360. They are in their own private reserved seating areas clustered with a few others cabana guests! Thank you hope to see you in paradise soon!
