We have enjoyed this trip with "Mocanita" a lot! Too bad you don't get to go further.
When you buy the tickets you also get the map where the attractions are listed. If you want to leave at 9 o'clock, then be sure to be at the ticket counter latest at 8! Otherwise you will get into one of the other 2 trains which leave from half to half an hour (only 3 trains a day!).
You can make a reservation, but only if you also buy food! We didn't, and we've eaten very good up in the mountains, at the last stop - you can buy grilled sausages and pork meat, but also beverages.
Even of you go during summer take care and bring some sweaters is it can get quite cold up-there!
Other than these, we've enjoyed a lot our visit here!
