We did a back-to-back in May that was very enlightening. The dock personnel may want to start getting you on ASAP but that's not the case with the poor cabin stewards. They closed the fire doors and had signs that asked passengers to remain in public areas until 1 P.M. so they could make up all the rooms (unfortunately many rude people ignored the signs). Have heard the whole fleet does this but it still went very quickly, Robbie
We always go at about 10 and usually they are already boarding. You may not be able to get in your cabin but what we do is take our bathing suits etc. in our carry on bag so we can lounge around the pool.
All of the above posts are right on - however, in the last two cruises we sailed, the pools were empty on departure afternoon. Bummer. However, the Windjammer is open for lunch and there is a great opportunity to scout the ship for public venues, such as the lounges, casino (closed while in port), theatre, dining room, etc. This is also a great time to find the Maitre'D if you have any special dining/seating requests.
