I was happy to find this thread as I posted a similar question elsewhere with no real result. I'm very surprised with all the point/miles tracking there is not even a portal to do this with that I've found.

Different note: I've done Carnival (hated it) and RCCL twice and had a good time. I was really hoping to do Seabourn this time...smaller ship, gourmet meals, few announcements in your room, bigger baseline cabins. However, hubby says looks pretentious (having the staff stand in the water to serve you caviar and champagne is a bit over the top). Wondering what your thoughts were about other lines that would be worth checking out.
