My wife and I were in Athens in 2018 and used the Hop-on/Hop-off bus and did find it useful. It saved us a lot of steps and we did frequently get off the bus to see points of interest. As I recall, they also included a pretty reasonable map that helped us get to where we wanted to go.

It appears that our ship (NCL Jade) will be in Mykonos on the day of Easter for the Greek Orthodox Church, April 16. Will much be open on the island? Our prior visit was approximately 5 years ago and we had a great time renting a 4-wheeler ATV and driving around the island. We're wondering if businesses like this rental location or other businesses will be open or closed on Easter. Does anyone have knowledge of this?
