My husband and I plan to do Croatia and Malta in the August of 2020. If we land in Zagreb, from Toronto, and plan to drive to Ljubljana, would we have any problem in crossing borders into Slovenia? We want to rent a car from Zagreb right upto Dubrovnik, covering 8 days. Is this a good plan? We are in our late 50 s and looking forward to a relaxed trip. Any advice will be very appreciated. Thanks in advance!
Very grateful to this Forum, from where I had planned my last Spain-Portugal Trip.

You shouldn't have any problem crossing the border into Slovenia. Just remember that you must purchase a vignette when you cross the border to drive in Slovenia. Otherwise, you will be charged a fine. The vignette is in lieu of paying tolls. You can purchase the vignette at gas stations. You should ask if you can buy the vignette at the car rental office in Zagreb.

Can you give a little bit more detail about your itinerary? We did rent a car in Dubrovnik and we returned it in Zagreb. Then we took the train from Zagreb to Ljubljana. If you are traveling to islands by ferry, then you might not need the car the whole time. It depends on your itinerary.

Whether it's a good plan is hard to say!

First, do NOT rent a car until you've been in the area for at least a day. Driving after crossing several time zones is just as dangerous to you -- and everyone else on the roads -- as driving drunk, and there is absolutely nothing you can do to avoid the risk. Not sleeping on the plane, not drinking caffeine, not monitoring each other -- NOTHING. You might not even notice the microsleeps that seem to be the primary cause of the risk.

Have you determined whether you can see and experience what you want in the time you have? I took more than 3.5 weeks to travel that distance, and I travel HARD -- on the move every possible moment.

As KarenWoo has mentioned, you'll need a vignette to drive in Slovenia.

If you don't already have it, I'd urge you to consult the Rough Guide to Croatia.
