We were dissappointed with our cruise especially since we have sailed on Royal Carribean and were very pleased. It seems that the Mariner has cut back in many areas to save costs. Our getting on the ship took a very long time...about 2 hours...and getting off was not as quick as we would like.
We had two terrific waiters in the dining room and the food there was good but not exceptional, i.e, the French Onion soup was more like a broth without the layer of cheese on the top....they have eliminated the lobster and surf meal and did not do the Baked Alaska desert. We did not like the buffet lines and food at the Windjammer Cafe...it was like bumper cars going from one serving line to another....they should have two long serving lines instead of the multiple serving stations....the Roast Beef and hamburgers are cooked way too much.
The interior cabin room is small at 167 square feet so consider getting a larger one.
The fitness center is terrific, two great instructors who gave free Stretch Classes and Talks on Physical fitness and plenty of workout equipment, the staff there is very nice and helpful.
We did not like the two R.C. Singers and Dancers and Orchestra shows. The Orchestra plays way too loud drowning out the singers.
The other problem is that they allow smoking in a number of the bars and Casino. The also need more musical groups in play in the bars and lounges expecially before 10 PM...it seems like everything starts after 10 PM.
