Here is what I would do.... 
 
Crowds, always perpare for the worst, if it is not crowded, that is a bonus. 
 
Personally, I think Mooseburger Lodge is the best food and value in the park.  OUTSIDE the park, 3 miles South on the 5, is an In & Out Burger.  You can leave the parking lot and come back the same day without paying again.  Just keep your parking stub. 
 
The maps stink, but thay are available. 
 
Strategy:  Since everyone floods Goliath's queue so quickly, and the fact that a 3 train operation is really fast on that sucker, wait till mid-day for it.  When the park opens, take the "Orient Express" to the top of the hill and hit Superman first.  Do that 2 or 3 times because NOBODY makes it up to the top of the hill for a while.  Next, hit Ninja because it will also be a walk on (if open). Then down the hill the other way to Riddler and Batman.  Both should be near walk ons. (Riddler for sure)  The rest of the day, you are on your own. 
 
The monorail is horrible.  If it is open at all, it will most likely have only one train going, it does not take you very far, and is not worth waiting for, IMO. 
 
Hope this helps, have fun!!  I would meet up with you, but I have to work. :(
