Welcome back, RavenDays!
Thanks for the report. I've stayed in 1A cabins a few times and found them to be just fine other than bumping my head when I had the bottom bunk and the upper was down. It is a common misconception that they are that much smaller than the 4A's, if any. This is most likely due to the odd cabin configuration.
I hope they find your memory card, and you get it forwarded to you. I bet you will double check the safe from now on!
Hopefully, a honest person will find it and turn it in. They are pretty good at logging in lost and found items.
