One Yes, it is 1 hour by train from Paris. Marine la Vallee station is
2 min walk from Disney security. Once through security the that's it done with for both parks.

Disneyland could be done in a day if attendance figures are low.

Compared to WDW we consider the following to be better in DLP...

Buzz
Space Mountain
Big Thunder

In studios...
ToT is same design as California.
See Cinemagique & Animagique shows
Must do the Crush rollercoaster
Armageddon is interesting
Rock n Roller we thought was worse than in WDW.
