Mariner vs. Explorer

[C.V.]

We have been on the Explorer and we are going on the Mariner, just wondering if there are any differences on the two ships. Also heard that there is a charge for Johnny Rockets on the Mariner, if so is there somewhere else the kids can go for a burger? How about pizza?
Thanks, Cheryl

We haven't been on the Exployer but have been told they are basically the same. There was a $3.95/pp cover charge plus drinks when we were on the Mariner last year. We have JR close to home so we just enjoyed the hamburgers at the Lido Grill outside and they had pizza in the Windjammer.
