We have a rough itinerary and I'd like any input you might have:

Day 1: Drive (early) from Venice to Istria, visit small towns, maybe see an Krk or Rab, stay somewhere in Istria

Day 2: Drive to Sibenik and stay there for the day and evening

Day 3: Split for the day, to Dubrovnik after dinner

Days 4 and 5: Dubrovnik

Day 6: Drive back to Italy or take ferry back

Does this look do-able? Are we shortchanging ourselves by spending so little time in Split and Istria? We had heard that Sibenik is more "true Croatian" than Split so liked the idea of that.

Also, we are going to be in Dubrovnik on Nov. 1, All Saints' Day, which is a holiday. Should we expect that nothing at all will be open that day including restaurants? We figured we would spend the day visiting churches since they will likely be open and walking around the city walls and heading to the beach.

Thanks again for all of your help.
