Shorter, narrower and softer skis make it a lot easier to ski in the bumps, but learning the techniques will go a long way in being able to ski them regardless of the equipment. The biggest hurdle is looking down the bump line instead of at the bump immediately in front of you. Once you can get over the fear of not looking down, things start to click.
Is it one of those Bumps for Boomers clinics?
They'll probably work on the backsides (green line) first and move up to zipper depending on the abilities.
You also probably have the luxury of natural bumps instead of man/machine made ones like we have back here.
Have fun with it!
