Translation of Appointment+

I have looked a little into this theme, and have some questions :

1) Can I translate it to Danish

2) As I am going tom use it as booking of tennis courts – I found out that I had to create each court as service provider to get it to work, and that is OK as long as I can translate the leading text, but what I noticed was that the same user could reserve several services the same day – is it possible to restrict the service so that one booking must be finished before the next can be done – and off course the administrator should be able to reserve courts unlimited for tournaments etc.

3) Even if I activated the add-on I cannot see who booked the service, did I do something wrong here ?
