Looking for feedback on Mariner of the Sea for kids

I know the Mariner of the Seas hasn't had many sailings since it was refurbished. I am hoping to hear some feedback about the boat for families with small kids. Our kiddos will be 4 and 6 next summer. Thanks in advance.

We just came back from the cruise with two families with a kids range 13, 12, 10, 8 and one years old. Food was great and u can get variety of fruits, we also send kids to kids club for a few hours, which was ok they said. Pool has ocean water. The slides and jumping has hight requirements, so you may need confirm if you kids can do it. Family karaoke and ice skates was great

Bring long pants and socks if you're planning to ice skate...it's required!

FYI, the salt-water pools are filtered, so unless you TASTE it, you won't know it's salt-water! Nice and clear!
