I know if you book 8 cabins at one time, that constitutes a group. What if you start with an initial set of cabins well under 8, and over the course of a month or so, the number swells to over 8 (all via individual bookings). Does this still constitute a group as far as discounts are concerned?
Your assumption about the 8 cabin requirement is correct. Back in 1999 I started
out with 4 couples and we wound up with 8 couples and 8 cabins. Each couple
made their own arrangements, but with the same TA of course. As the group
leader I received a free cruise, but what I did was share it with the other couples.
If my memory serves me correctly, we each got a discount of something like $125 which I thought was pretty good.
