What's interesting is the new phrasing used here:
https://www.royalcaribbean.com/mex/es/faq/questions/what-are-the-benefits-of-the-key-program
"Access to the fast lane at onboard activities (activities vary by ship)and private time at the Flowrider"
Has anyone experienced this? It seems that there's no longer a "private" time for Key guest, now is a "fast lane" anytime.
