We usually stay in cat 4's and paying two adults with two kids there, usually is MORE than a cat 6 with a cat 11 across the hall. We're doing the 6 and 11 (actually different cats now, but I don't know them as well as the old ones) for Alaska. We really wanted a balcony for Alaska and the cat 4 for all 4 of us, was 2k more than the 6/11 combo.......
