A quick intro -- we are in the 55-60 range, very active lifestyles and this was our 2nd cruise (Bermuda cruise several years ago). We are not cruise experts by any stretch but I just can't believe all the people that spend the money and time to go on a cruise, then find ways to complain about their vacation!
We flew from Baltimore to Ft Lauderdale on the morning of the cruise with no problems. We got a ride from the airport to the cruise terminal by a relative in the area, arrived at noon and we were in our cabin by 12:15. Amazingly quick and simple check-in process. Even our cabin (mini-suite on the Dolphin deck) was ready. Very, very nice and spacious with an extra sitting room, a full bathroom and our first balcony (I will never cruise without a balcony again). Concerning the Dolphin exposed balconies...not an issue with us. It never got that hot, I didn't really care if people could look down on us (it was very rare that anyone else was out on their balconies anyway) and it made the cabin feel that much more open.
The ship is beautiful. We spent the first few hours exploring the dining rooms, buffet areas, pools, lounges, casino, library, internet area, etc...
D317 - Dolphin deck, convenient location to the elevators and stairs, quiet. We enjoyed the exposed balcony.
