Transportation Venice to Ljubljana question

About a decade ago I did this with a bus to Villach, Austra to transfer to a train into Ljubljana. I can’t remember if it was a single ticket, but everyone on the bus was catching a train. I have no idea if that is still the best route or not.

We took the Flix bus from the Venice airport to Ljubljana. I see they also run a bus for Piazzale Roma. It was very comfortable and just over a three-hour ride. This is the website: https://www.flixbus.com

I've seen multiple positive comments about the company GoOpti on this forum. I know one of the routes it runs is Venice-Ljubljana. I cannot tell you the cost--surely a good bit more than a bus but I believe less expensive than at least some other transportation options (like Daytrip.com). I've read that with GoOpti you have a choice between a more expensive, fixed-schedule trip and a less expensive trip on your date but at a time of the company's choosing. I think GoOpti uses vans.

Go -Opti is a good choice.

We have used Daytrip.com multiple times, and always had great success. Their cancellation policy is very generous.

I am traveling in May Venice to Piran and then onto Ljubljana. Train from Venice to Trieste and then you can go onto Ljubljana. I take Flixbus whenever I can, always on time and always get seat IC, aisle by the door so driver does not block my view.
