What I was told by a RCCL C & A staff member back in November, 2015 was that in May, 2016 there was going to be an announcement. The changes were going to be:
P level elevated to 1000
DP level elevated to 340
No more double points for JS suites
Everyone would be grandfathered in if they are already at the levels.
Im a DP member with 305 points. If they were to not grandfather me in, Since Im so close to the new DP point level, I would just enjoy the D bennies and then get another DP recognition reward etc. when my DP Status arrived again.
