If anyone is planning to go Ancona-Split next year then I'd recommend having a look at the SNAV website.
www.snav.it
I've just priced up and for 2 people, 6.50m van, outside cabin it comes to €235 (saving of €93) I also put in a larger vehicle and the price was the same. Thats travelling mid-September. Last year travelling mid-July it was about €250 for the same thing.
Just make sure that on the second page of the booking process it has BLACKSNAV at top of page.
