Overnight stop from Prague to Zagreb and other things

We've been motoring quite a lot from Prague to Zagreb in the last year or so and with a small child we did it in 2 stages. We first stopped in Graz, then somewhere else, and, from a tip, we finally settled on a hotel in Windischgarsten which is about exactly half-way between P and Z on the A9 going down to Graz. The hotel itself (http://www.sporthotel-fuerst.at/index2.htm) is (in no particular order) a) extremely comfortable and cosy, b) has amazing views (each room with balcony), c) is run by a very cool, relaxed and friendly couple, d) has a well stocked bar, and e) has great breakfasts with home made salamis, omelettes made from the freshest most eggy tasting eggs - or, if you are more inclined to healthy stuff there is muesli, fruit etc. there are a couple of ski resorts within striking distance (regular bus from Windischgarsten) and is obviously great for walking/outdoors stuff. The hotel also has a garden with a tennis court, and a very small swimming pool. Oh, I almost forgot, they have a sauna too. The whole experience is very relaxing and highly recommended. The only downside we found is the food in the town (the hotel does not serve food apart from breakfast so you have to forage) which is ok, but not great - certainly no ethnic stuff around. But if you are used to Germanic/Czecho food, it will be perfectly acceptable. On the nutrition front there is a really really really good schnapps shop on the main square - my tip is the one made from vogelbeer - took some time to find out what these things were in English - rowanberries.
