Jade question: pools, relaxation area, adults area ???

We have sailed on several NCL ships but not Jade. What is the "Relaxation area"?

Is it complimentary?

Is there an adults only pool area?

Reflection had a Solarium. Anything like this on Jade?

Unfortunately no adult only solarium. The Jade wAs one of my all time favorite ships, but I was on a norway itinerary- not sure she would be my first choice in the Caribbean for this very reason.

Is there a charge for Solarium on Jade?
