We know that we can catch a bus from Trieste to Opatija, departing at 08.30 or 13.45 on Thurs 4th Sept.
We arrive in Trieste the afternoon of the 3rd Sept .
My questions are:
Should we try to buy our tickets on the afternoon of the 3rd for travel the next day?
If so, what time is the ticket office open till?
Can we expect to be able to buy them on the day ?
