In addition to crowd noises, a raffle, and tours, you also need to do something with your carry-ons, complete the muster drill, and consider what to wear, depending on the service you seek. Pebbles has a 3:45 massage on embarkation day, which allows for checking carry-ons in the cabin (usually available at 1:30) and still gives her time to unpack, shower, and get ready for dinner at 6:00PM. Lots to consider for such an early reservation. Good luck!
