I agree, one flight should be enough. Ground effect is more noticeable in low-wing aircraft. Actually I think it would be sufficient to sit in the airplane and go through the checklist several times and touching all controls so you know where to find them. To me, a transition to another plane is more about the panel layout than about the airplane (as long as we're talking about PA28, C152...). Anyhow, I appreciate to fly from time to time with an instructor/"rated" pilot.
