No matter what pond in the world you go to bass will eat worms! Make sure you bring a trick worm or senko
I've had bass turn down jigs where no craw are in the ponds, same with cranks/jerks...but never had an issue with a fish turning down a worm.
A spinnerbait is always good to!
edit: Better advice than mine:
"I would suggest you stock your tackle box with a vareity of things but you don't need to overdo it. Cover your water column, Topwater poppers or frogs, spinner baits, jigs,soft plastics (worm/craws) and a couple of cranks to cover different depths. Ask your friend about the water clarity to help choose your colors. You should be ready for anything."
