What kind of fish are you after?
I was looking at the dates that you are going fishing and if you would drive a little farther than two hours, you could do the derby at pathfinder that weekend. The have hourly prizes for the largest fish and second largest fish and many other door prizes... who knows you may get lucky and win something.... Good luck...
Not too many places around here with panfish. Granite has perch and trout. Pathfinder has trout and walleye. Yes there is plenty of lodging in Casper which is 30-45 miles from Pathfinder. Rock lake is near wheatland but the ice may be no good, it has walleye, bass, catfish, and panfish I believe. Where ever you choose, good luck!
