Mariner is a great ship. It was the first ship I ever went on, and it definitely is a paradise at sea. DJCarolina has been on it the most, I think like 10 times haha, so he really knows the ins and outs of the ship. I have been on Mariner 3 times. Some of the things you can't miss are the ice show, "Fue" (the teen dance club), and all of the day at sea pool activities (belly flop competition, sexy legs contest, e.t.c)! The food is great, I highly recommend the desert "baked Alaska" It is SOOO good. If you have any specific questions feel free to post!
