General: My family's second Disney cruise following an Alaska run last year. This time we went with an extended family group (7 adults, 7 children aged 9, 7, 4, 4, 2, 2 and 16 months) on the post Thanksgiving Western Caribbean itinerary.
Pros:
Embarkation-Getting on is really a breeze unless you are trying to board right as boarding opens (which is really only important if you are trying to reserve something, e.g., Remy or Palo, that you couldn't get online). We got to the port around 12:45 and were on the ship within 30 minutes of port arrival.
