You must be at your station for the life boat drill by 4pm. All persons in your cabin are required to attend. By 4:15 pm, the drill is over and you are back in your staterooms to put away your life jackets.
Then, head to either deck 9 or 10 for the sail away party. It starts at 4:30 pm; the horn plays that sweet, sweet tune at approximately 4:45 pm - 4:50 pm., and the party is about over. However, if you do not have to rush back to your stateroom, hang out on deck 4 at 5pm when the ship leaves port and watch the CMs waving goodbye. Also, it's fun to wave to the folks along the waterway as the ship is heading out to sea.
This is a quote from the Navigator (we sailed the Magic on 10-4-08):
Under the 3:30 slot on page 2, it says: "All ship services will be suspended during this time for the mandatory board drill scheduled for 4:00 p.m...." The Navigator does list the sail away party as starting at 4:30 pm and ending at 5:00 p.m.
Enjoy your cruise!!!
