When we went we could have packed in two carry on size suitcases, but it's Disney LOL. We both took our larger bags (I think they are 25'') so we had some wiggle room for souvenirs spacewise. The picture I posted was everything we brought back except for 2 tshirts and a mini TsumTsum, so we weren't really worried about weight as it was a short trip and we both were light on the way out.
However I now remember that two of those mugs we found in the SNA airport on the way home so those must have gone in one of our carry on bags. So only eight were in the luggage.
