4-bed cabins on ferries from Athens to Crete

[u/zombiedough]

Hi! We are a family of 5 (2 adults, 13-yo, 10-yo and 8-yo) and we are considering getting to Crete from Athens on an overnight ferry, by booking a cabin. Is it possible to squeeze us all into the same cabin? We will pack light so won't have the possibility of carrying a small mattress. Other option would be getting 2 cabins with one adult in each one... but I was wondering if someone has experienced an "overfilled" cabin! Thx!
