Except for the taxi from hotel to Avignon Centre that was supposed to cost 10 E but was really 15 E, everything went swimmingly.
Train to Vitrolles (5 minutes late), roll the bag down the ramp, a little wait for the free shuttle (regular city-type bus, no rack for luggage) to the airport. It makes one stop, but should make three for the three buildings--term 2, term 1A, and then term 1B--so you gotta look around for which way to go. Could be a problem in a pouring rain--no cover. Luggage cart there for a euro/return when you get off bus. Too early even to check the bag, had lunch, spent the rest of the euros, no line at all at security--somewhat strange though, what's the little paper they are wiping on some of my things?
Only one sandwich place and convenience/newstand on the other side of security, so have a good meal before security.
In the air for 50 minutes from Marseille to CDG.
So I was glad I didn't spent money on a hotel near the airport in an ugly industrial-type zone.
