Good service - but quite pricy for what you get. Direct access to the spa next door. Free wifi access. Beds extremely comfortable. All and all a good experience!
Take your time going round the tour. Don't rush it. There is so much information to take in. Finishing with cinema is a good idea, before the Cafe and buying of chocolate.
Before you enter the castle, take the path that goes around it to see the view. Then if you have a Raiffeisen Maestro or Credit card, you can show it at the cashier and you get one free entrance :)
