Deck 5 cabins on Ventura are unobstructed....the lifeboats are higher up....deck 7 I think. The only point that may concern you is that the cabins towards the front are fixed bed so only twin formation. TBH can't remember if P221 are fixed bed as we always prefer twin beds....seems to give more room. As I said one of the reasons I love deck 5 is for the convenience and the convenience of not having to use lifts....I hate being in crowed lifts
