How to get from CDG to Orly airport

Perhaps all transport in Paris other than metro/RER is expensive, but this one was a whopper! I needed to get from CDG to Orly airport in a fairly straightforward manner to get on my flight to Malta. I also had VERY VERY heavy bags and was traveling alone, which rules out metro/RER since most of them don't have escalators. Luckily, there seemed to be a direct bus, run by Air France from Terminal 2B Port 2. Every half hour or so, Air France shuttle #3 arrives and goes directly there. I think this bus might stop at a couple of other terminals inside CDG, but the advantage of walking to Terminal 2B is that it's the last one before hitting the road - no more picking up passengers, and the bus never seems to be more than half full.

Price: $19 Euro each way, no roundtrip fare offered.
