Yes, I did, it fast and much cheaper than a Taxi, but you have to walk about 150 meters to the gate.

Hi Going through the city is free, but getting on the wall you have to purchase a ticket and there are some stairs which is difficult to get a person up in a well chair.

I am sure they would take euros. I do not have a cost, but don't feel it would be very much. I cannot help further as we took a bus to Dubrovnik then caught a local bus to the Pile Gate and it was very inexpensive.

Most places only wanted local currency

Die Kreuzfahrtschiffe halten ganz woanders. Mehrere KM entfernt. Taxi sind nicht so teuer.

I can't add much more to what others have said. But... From what I remember we did walk down that way. It is relatively easy walking from the Bus Stop down the main street in the centre of the old town, then at the bottom of that it looks like you turn off to the left according to Google Maps. I think that you may encounter a few steps along your route but towards the end but mostly there are sensible ramps. There are cobbles though so be sure of your footing in the wet as they can be slippy.

Why you don't publish that note here at the Forum for Croatia too? ShowForum-g294453-i1554-Croatia.html

Sorry I can't help but you could ask the tourist information office just across the square 100meters
