Last summer I did a family trip to Greece.
At times it was not handicapped accessible and my transport chair was hard to maneuver on cobblestone sidewalks and streets.
There was also issues in some museums my family went to, having steps was a negative for me,so I sat outside while the rest of them went in.
I was not able to go to the Parthenon either, because of the rocky terrain, but I had been there 20 years ago when I didn’t have any mobility issues.
The island of Santorini was a nightmare because of the narrow stone walkways and tons of steps that my husband had to push my chair on.
Also it was extremely crowded, and hard to get thru the crowds.
On the other hand,taking the ferry back to our cruise ship was very easy, and the staff had a ramp and pushed me onto the boat.
I did have a good time on the trip, but I often felt sad that I had this mobility issues, and it did put a damper on my trip unfortunately.
