Overnight train from Budapest to Split

I am not familiar with that train, but according to the Deutsche Bahn website, it has both sleepers and couchette cars, and no transfer is required. The train makes 17 stops between Budapest and Split, though 12 of them occur before midnight. Even when the ride is smooth, it is difficult for me to sleep through the braking and noise that occur with each stop.

I went to the MAV website. It is popular, as there were no sleeping compartments available on the 2 days I checked for next week, but there were on date a I checked in September. 316 EUR for 2 in a sleeping compartment.

I discovered Montenegro a few years ago and love it enough to return this year. You might consider the direct Budapest to Podgorica flight for about $100 and then move up the coast to Dubrovnik and Split. You can also fly Budapest to Belgrade to Dubrovnik.

Thanks everyone for your comments. 17 stops does not bode well for a good nights sleep! Does anyone know what the actual sleeping accommodations are like? Are there private bathrooms?

The Seat61 link above has a description and a photo. While he describes the cars as comfortable and refurbished, it's a very standard night train, with nothing so fancy as a private toilet, nor the extra price tag that would usually come with that.
