We just cruised in a CAT 10 Inside Stateroom that slept four, room 2141. It was a great room, would stay in it again if I would cruise again. It was exactly comparable to a Verandah room on the 7th floor that I saw, without the Verandah of course. Can't say I would spend the extra $$ to upgrade. I actually liked the complete darkness at night and the sligh hum of the engines. Otherwise it was very quiet down there, with exception of rude and obnoxious people that can't keep their voice down in the halls early in the morning, but you could have that in any hallway.
