Trieste to Slovenia

[suekel]

We're doing a Princess cruise in the future that ends in Trieste.  One of the excursions offered on disembarkation day is a day trip to Slovenia.  I'd really like to do it but...after the excursion you are taken back to the ship.  It doesn't say it's for B2B passengers only.  I'm not too concerned about having to go from the port to the hotel or airport depending on flight times but curious what happens with luggage.  Anyone have any experience with an excursion like this?  I'm getting on a cruise in a few days and can ask at the excursion desk, but I'll be surprised if they know.

The luggage will go in the belly of the bus.
