When we had the JS
, we did get priority boarding in that there was a special line for those with suites.
A RCCL person was walking down the line for check in just sort of making sure everybody had stuff ready for when they hit the desk. She noticed we had a JS
and took us to another much shorter line where we were through in minutes.
This was in San Juan, so I can only speak for that port.
As for anything else special, we didn't have any.
