We were originally planning to spend two nights post-cruise at the IC Moorea using an Ambassador certificate, but the IC Moorea is already full that weekend. So I booked two nights pre-cruise, but can’t use an Ambassador certificate because we won’t be there on weekend nights. However, I just reached Priority Club Platinum status, which apparently entitles me a free room upgrade at IC hotels just like the Ambassador Club would. Now I’m wondering if I should bother paying the $150 to join the Ambassador Club since I don’t know when I’ll use the coupon and should be able to get the room upgrade with my Priority Club Platinum. Has anyone had experience receiving a room upgrade at an IC hotel with their Priority Club Platinum? Should I contact the hotels now for a room upgrade in November or wait until we get there?
