On all the essential categories the Solstice scores an A.  The food and specialty restaurants were excellent.  The service from the highest to lowest crew members, was great.  We did not meet one crew member with a negative attitude.  The decor of the ship is beautiful, and we have been on many ships with at least 15 cruises to date.  Although there were close to 3,000 people on our cruise, it never seemed crowded.  We enjoyed this vacation as much as any cruise we have ever taken.Although I would recommend this ship to anyone, I do have two concerns.  First, the Solstice has done away with a prominode deck that often circles a ship.  Many older guests love to make use of this feature as it brings you up close to the sea in a peaceful walking or reading environment.  What has replaced it is a running track on an upper deck where people are also trying to walk, for relaxation and\or to get to a different part of the ship.  It is a very active zone dividing other parts of the ship.  This area is also near the pool.  Together this makes a mixed venue that I believe is very unsafe and is trying to cater to walkers and runners.  It just doesn't work. Second, Celebrity had a fine program on all ships to encourage the booking of a new cruise, (an advantage for the cruise line and the guest).  You would have made a down payment of $200 and received an on board credit based on the days of the cruise.  You were allowed to switch from one cruise to another if you were unsure of your original cruise choice, at the time of this special booking.  In unbelievable corporate short sightedness Celebrity recently changed the rules.  Now if you changed your ship booking, the down payment jumps from $200 to $900.  Inspite of the hard work of many many crew members as cited above, the poor judgement of management gets a grade of F.
