I haven't quite figured out the system, I do like how I can do many back to backs in a row. I had 48 days then next day was booked from another port for 30 in Europe.
It varies a lot some I get signature suites with like anywhere from 500-1250 free play and drink package.
Then the casino insiders offer gives me an O/V 650.00 free credit no drinks and some have same sailings as the way better offer. So I really must pay attention.
