Don't host Austrians, but host germans. Ad far as the food, at least in our family we eat a very vegetable heavy diet. Is say 75% of our plate is fresh vegetables. I've found that ALL of our German APS were heavy meat eaters and missed the carnivorous feasts.
We've been hosting APS for a long time and long ago adjusted our bread habits and are now addicted to fresh bread from a great local bakery. We even sometimes get Stollen

and yes, typical American bread is awful, absolutely the worst.
