Very Disappointing

We were not wowed by the newest cruise ship. The first night we asked for a table for two by a window and were told that the tables by the window are for 4 people.  We sat away from the window and throughout our entire meal - no one occupied the tables for 4 (which were two - tables for 2 pushed together). After speaking to the manager -  telling him that is staff should find a way of saying "Yes", we didn't have that problem again. Many members of the staff didn't understand English.  They've tricked us into thinking we are  "Guests" but the truth is we're "Customers" and there's nothing wrong with that. Guests in my home don't pay. They're truly guests. The North Star ride got stuck with people in it, while I was on line to get on. It remained broken the entire cruise and I never had that opportunity. The elevators were operated by computers but couldn't handle the number of passengers-very slow.  Even though we scheduled appointments for dinner and shows, we had to wait on line for most things.  The staterooms were spacious, and quite nice.  One evening the ventilation system in the kitchens failed and dinner wasn't started until 8:30 pm. We were all forced to go to the buffet and received a 10% reduction on our next cruise booking. The entertainment (Mamma Mia, Star Water,) were excellent. The singer and ventriloquist left much to be desired. The Thermal spa was very small, co-ed, and not worth the money.  We've cruised a great deal and since the ports are pretty much the same,  the cruise experience is what we're interested in, and it seems Royal Caribbean doesn't have a handle on that. Food was good.  The soft ice cream machines were broken most of the time and there were no substitutes.  Needless to say we were disappointed in this cruise. Will probably stay away from the megaships and Royal Caribbean.
