We just returned from the Legend. We've been on several other Carnival ships, but this was our first spirit class ship and I think it is my favorite. Not too big or too small.
FYI, my family consists of myself, my DH, and 2 DDs ages 13 and 11. We were traveling with my DH's sister, her husband and their DDs ages 16 and 17. All of us have cruised several times before.
We booked 2 extended balcony rooms (7195 and 7199) for the adults and 2 inside cabins across the hall for the kids.
Excellent cabin. Not too far from the elevators, only 2 decks down from the Lido. Very quiet. Extended balcony - loved it. Very shady most of the time.
