Would you be happy with low'ish hours to just jump into a PA-28 and fly across the world on your own with no experience of this kind?
As always its horses for courses. Chap from Perth flew around the world in a Mustang II home built and had a grand total of 250 hours when setting out. On top of that he had no instrument ticket and made the trip VFR.
Have a great trip PlankBlender, only wish I had the background to put up my hand to come along.
