hi Kanayo
take the coach bus , its better and cheaper , CTM lines.
from fez to meknes some 30-40 minutes.
meknes to el jadida 250km : 3-4 hours maximum
meknes to marrakech : why not to stay in rabat and casablanca for one or two days alot to see there especially the hassan 2 mosquee and the royal palace ? anyway , meknes to rabat is 105 km highway from the west station so you can calculate your self, should be 1 hour maximum. rabat casablanca 65 km : 30-40 min , casablanca marrakech 2h - 2h:30
there is a new highway connecting marrakech and agadir , agadir is a nice place too to see , african miami somehow
