Do catamarans sell out in August?

[andrewjohnwilson]

Hi there,

Just planning my trip to Croatia around August 18th - August 28th.

I've made my itinerary and finally worked out the ferry/catamaran schedules.

Just a bit nervous, as so many people seem to be going to Croatia this summer...

Do the catamarans, especially the Jadrolinija ones between Split, Hvar and Vis ever sell out?

It's such a shame you can't book tickets in advance as would give me real peace of mind!!

Any advice/help much appreciated

Thanks,
Andrew
