Pressman,
NAC have a Seminole which I completed my Multi rating on.
Already been speaking to them (a while ago) and they'd have no problems in me taking it away for a week or two as long as the aeroplane is flown at least four hours a day on average. I'm quite flexible on when this will be during the year so will fit in with their student schedules.
To fly the Seminole solo, they require over 300 hours total time including 25 hours of multi including a completed nac multi course. If you haven't completed your multi at nac then it'd be 50 hours multi including 10 hours on a PA44.
Interested in a trip yourself?
All the best.
Charlie Zulu.
