I am looking to plan a day trip to Mljet next month (specifically August 10) from Dubrovnik. From what I can tell, our best bet will be to take the Nona Ana ferry leaving from Dubrovnik at 9:15am, then leaving on the return leg from Polace on Mljet at 4:55pm. I was on the Nona Ana website trying to buy tickets (https://gv-line.aktiva-info.hr/eng/frmPregledSlobodnoEng.aspx) and noticed that they were "not available" on this date.
Wondering if any of you have used this ferry service before (operated by G&V Line) and if so, when / where you bought tickets. Apparently you can line up at Gruz port an hour before and buy tickets, but I would really prefer to buy in advance online if possible.
Also sent an email to them. Thanks for the help.
