Actually, there is a chart that shows the breakdown, I'll see if I can post it. Obviously it's by days cruised. SO, if you take one cruise that's over 25 days, it's 2 credits. Nothing to do with the number of bookings. For example, a person can book an Around the World Cruise and in ONE booking get 15 credits and automatically be at the Gold level when they step on board, even if they've never been on Oceania before. Also not looking to argue, just trying to explain to you how the Oceania program works. I've been doing this for a while now, so I'm pretty familiar with the drill. As to your other post, yes, awarding points by cabin level and amount of money spent is very much class division mass market stuff.
