In looking at Elite Benefits, it looks like Persian Garden access is offered as a perk, for one port day. I’ll be sailing soon on Silhouette. Can anyone tell me how to take advantage of this benefit? Will I be required to make a reservation once on board? Are there a limited amount of “day” passes available? Is Persian Garden just a “upgraded” section of the spa…and, there are other areas of the spa that all passengers would be able to enjoy at anytime? Or, is the entire spa section (with exception of gym) pay extra only? (We were recently on RC Serenade; we could use same-sex steam room, sauna, shower (all part of locker rooms), and a quiet area as we wanted. Upcharge area was available—with tiled loungers, co-Ed steam, rain shower, etc). Any insight is appreciated.
