I rechecked and I should have said those with 5 or more credits got 3 bonus points plus 7 points for each credit. Those with 1-4 credits only got 1 bonus point.
Nobody got demoted in the new C&A plan, but some platinum members (8 or 9 credits) got promoted to Emerald member.
The new levels are:
Gold: 3 points (one 3-night cruise)
Platinum: 30 points
Emerald: 55 points
Diamond: 80 points
Diamond Plus: 175 points
Pinnacle Club: 700 points
