My DH and I are going on the Dream in January? We have sailed DCL 4 times previously, so we feel we know the ropes. However, this time we are without kids! We are looking forward to actually seeing the adult only areas. We are concierge and are planning on booking a cabana. We had cabana #5 on the FB in 2011. We are interested in serenity bay. What can you tell me about that? We also are debating staying on the ship at Nassau or Blue Lagoon beach day. What are everybody's suggestions? Feeling like a newbie because its the first time without kids and we are excited! TIA!
