I stayed in the same cabin on Navigator, directly under the Windjammer.  We never heard anything from the Windjammer.  The only thing we hears was the music from the Flowrider when we went out onto the balcony (and they do play the music 24/7 up there for some weird reason), but we couldn't hear it in the room, even with the balcony door open.  Highly recommend.

yep, Greece and Croatia, Sept 2023.  Can't wait!!!!

Short answer is it's not happening in 2021. No firm plans to have it, but Royal did say earlier in 2021 they intend to eventually do it https://www.royalcaribbeanblog.com/2021/08/02/how-royal-caribbean-invested-new-port-projects-and-tech-during-the-cruise-industry

They are open now

Jill - can you pass me the link as well?  Looking at one of the 2023 Holy Land cruises.

They're delayed to this week. 
I don't have a firm answer why, but deployments are not a simple task with so many variables (ports, ships, availability, etc)
