We spent 3 days in Marseille and made good use of the 72 hour City Pass visiting Chateau D'If (the boats don't always run if windy so check the weather forecast), taking the tram to Palais de Longchamps, the Petit Train to Notre Dame de la Garde, visiting MuCem amongst other things. The only thing that was disappointing was the walking tour of the Vieux Port and Panier district. We booked the English tour but were the only two English people on it so at every stop we listened to 10 mins of French and if we were lucky she remembered to give us 1 min in English (usually whilst walking to the next stop). This was really disappointing and the only walking tour we have ever had a bad experience on!. I would recommend the City Pass.

Very good advice given to me in the tourist office. My only regret is that I did not have time to see all museums etc. included.

Good way to see the town if you've got 24 hrs. We were on a cruise ship and couldn't take advantage of all the offerings.
