The best way for you to compare is to cruise another line and then make a comparison. I think the first cruise is the hardest b/c you are so full of "other people have said" that you alternate between being overwhelmed and just a bit disappointed. That alone can be exhausting. While cruising is addictive, you have to know what to expect.
The kids in the pool issue, well I think only the aft hot tubes are adult only. I don't think any of the pools on Liberty are adult only. And, even if they are, people are inconsiderate. What I found works is that I just wait until after 4:00 or so in the afternoon to enjoy to pool or hot tubs. By then most families with children are getting ready for dinner (early seating) and the pools are generally cleared of kids.
The pools are not lap pools. They are more cooling off pools.
As far as children running in the halls, call security and report them. Kids will go as far as they are allowed and sometimes parents do not understand that the boundaries acceptable for adults w/o children is not nearly as wide or flexible as it is with adults travelling with children.
I tend to take a late seating for dinner. That way the dining room, showrooms, pools, etc. are cleared of the younger set when I go to partake.
Now if you tend to go to bed early (pre-1:00 a.m.) or take afternoon naps, I suggest you reserve a cabin in the front or back of the Riviera Deck. You may hear the engine or anchor once or twice but besides those few minutes once or two time a cruise, these areas tend to be cemetery quiet for the rest of the cruise. The Riviera Deck feels less of the ship's movement, it is nestled beneath another deck of all cabins and the back and front of this deck has far less traffic. The best plus is that this is the cheapest deck on the ship.
