Not all of us a members of your elite circle at Amex Centurion. If you would list some to the promotions they offer (lines and destinations .. you can keep your special perks a secret since we would have no way of accessing them anyhow) you might get some responses.

August on any cruise line .. that MIGHT coop with Amex Centurion is a pretty big ocean for comments from the forum.

August is not that great a month for a Caribbean cruise (just a tad hot). Its also too early for fall foliage. I'm on the Queen Mary 2 New York - Southampton in August .. with a couple of days on the end is a 10 day trip.
