I'm considering a Symphony cruise (only done DCL in past). Most likely a regular balcony stateroom. I can't find pictures but keep seeing description "sofabed". Does that mean the kids sleep together on a mattress that pulls out of the couch? Or, is it a sofa that converts to a bed with the bed coming out of the ceiling above it like on DCL? I like the bunkbeds on DCL but they're not thick mattresses and not comfy. My daughter will be 15 and a little big for these flimsy mattresses. You pay so much $$ and can't get 2 real beds?! Ugh!
