A number of people will tell you that your first cruise should be relatively short...but my wife and I decided to go big with a 14 day journey aboard the Eclipse. We loved every second of it! Rather than gushing about the experience, here are some useful details:
1) Staterooms: We booked a cabin in the Concierge Class on the stern of the ship (a C1 Stateroom on Deck 10) - concierge class gives you some additional subtle amenities, but it's the location that is key. We will never stay in another location - the view of the ship's wake is mesmerizing, and alone makes it worth the extra money. Additionally, the balconies on the stern are tiered, so you have direct sunshine if you want it (rather than having a shadow from above).
2) Staff on the Ship: They were extraordinary. Everyone from our stateroom attendants, to our dining team in the main dining room, to the bar staff, to everyone we would pass in the corridors - they were extremely friendly and attentive to our every need.
3) The Ship: it was spotless. And for those who worry about getting bored, it never happened to us. There is always something to do. My wife and I like to just relax on vacation, but we found ourselves going to just about every show on the ship...even attended a seminar on Faberge eggs. Also, the gym is very nice and well appointed.
4) Food and Drink: the food in the main dining room was consistently excellent, as was the food in the Oceanview Café and through room service.
Bottom line - there are people in the world who love cruises and people who hate them. We loved it, and have already booked our next one aboard Celebrity (the Equinox this time).
We chose this stateroom due to its location on the stern of the ship. The room itself had more storage than we could have imagined. My wife and I unpacked four suitcases and two carry-ons (it was a 14 day cruise after all), and there was a place for everything. The bathroom, although small, was very functional. The bed was very comfortable and came with a range of pillows. Deck 10 is very quiet. You can't hear any noise from other parts of the ship, and it feels very private. But it is also just a few flights of stairs to the action on Decks 12 and 14, so you don't need to wait for elevators.
