We will be in Malta on 8/25 from the Celebrity Solstice Western Mediterranean cruise. We are docked from 8am - 5pm. We are considering the Malta Hop on Hop off bus, but cannot decide between the northern or southern route. Can anyone please advise as to which route is preferred. I am reading about the history of Malta, but can't get a handle on all the sites yet. Whichever one we choose, will they return in time for us to board? in addition one of the 6 of us (me) will be traveling with a prosthetic foot and a compact travel scooter. How accessible is Malta? Thanks!
