We took the VEA shuttle from CDG in 2002 because I didn't know about these boards and didn't know better LOL, but if there were quicker alternatives, I would definitely go that route....We either just missed a shuttle, or they were not true to their schedule, because we waited quite awhile for the next one to show up. On their site, or DLP site it says that they come every so often (can't remember exactly), but watched my clock and they were almost double what it was supposed to be. That and all the stops at all the terminals was a pain....even though only 1 other family got on.
If I remember correctly they stopped at only one hotel before ours, but there was only 1 or 2 other families on the bus, so it could have been who knows how much longer. I think we did pay by credit card...it's all fuzzy. All I know is the DL hotel was marvelous!
