We bought tickets for ferry from Korcula to Split on Monday the 22nd at 12:20. When arriving in the harbour, the workers said "Nema do Split, samo do Bar danas". When investigating at the sales office, they sent me on to Vela Luka (some 45 klicks away), where a boat is leaving at 14:40. And the ticket actually did work there, thou none of them information printed there matched the actual journey.
