Just returned from the Mariner and our Gold level gift was 2 picture frames (5x7). The frames are sort of a leather material and are embossed with the RCCL logo...frames are blue in color. The downside is the very cheap protector over the picture....very thin cheap plastic. However, it is nice to put a picture in that you may purchase onboard. Ours is sitting right next to me with a picture from the first formal night that we purchased.
From the last post, it looks like Platinum and above members get nicer gifts......luckily, we're now PLATINUM!!!!
