Just off the Pride had a great trip heres our take.
Embarkation: Fast and efficient did the early check-in thing, and we were on the boat around 1PM& We took two cars due to all the luggage, and found out afterward that was a mistake due to parking costs (its like $12/day each car anyone know of cheaper parking? Can you park at the Queen Mary hotel and walk?).
We have 3 kids (girls 12,11 and a boy 6), and we were traveling with the grandparents ended up with 3 staterooms with balconies. Grandparents have cruised all over the world (30+ times never on Carnival).
