Let's start off with an important caveat: This was the maiden voyage of Quantum so some of the things that happened on our cruise will hopefully not be indicitative of the new Quantum class product. I feel it only fair to point this out from the start in order to provide a balanced and fair review.
Ok, let's get going...
Appearance: This ship is visually WOW inside, especially when you compare it (as you naturally would) to every other Royal Caribbean ship in the fleet. There are the Royal touches that make you know what brand you are sailing with but then there are so many new elements which make you feel they have created a hybrid company between Royal and Celebrity. I can honestly say that this makes it the perfect combination of Celebrity style and finesse and Royal activity and excitement and we love this new era of sailing. The inside spaces have been carefully considered and there is a real shift of feel as you move about the ship. I especially loved the transition between the Via and the Esplanade. The feeling of serenity as you walk through the "empty space" with the butterflies and calming music is really well constructed.
These cabins are bigger, obviously in relative terms being a cruise, and look so much crisper. We were uber excited about being the first paid passengers and the first people to sleep in the bed (ok, we knew we weren't really but we like pretending!) but we got into our room and there was a half drunk bottle of wine in our fridge and the bathroom wasn't clean--not a great start. This was sorted promptly though but still shouldn't have happened on the first cruise. We also had an issue with the balcony partition which took two days to resolve (Guest Services are just as useless in the main on this ship as they always were--no point dwelling on this as Royal never does anything about empowering Guest Services to do anything!). Once sorted this gave us a great cabin, in a great location but the first two days were frustrating to say the least--also resulting in us having to sleep in another (unfinished) cabin on the first night after much complaining. This cabin is in a great location and central to everything at the front end of the ship and an easy walk to everything else.
