Travel Tips

I would recommend going to disneyland on a rainy day. That way the queues are down to nothing and you can do all the rides without wasting too much time.

Why do you want to book your tickets? Just go along. That said, you can buy combined entry tickets for the RER and the entry at the metro station.

The metro (RER) station is called Chessy, but it actually says Disneyland on the metro map.

At Wagram station, take Direction Galieni.
Change at Opera
Then take the RER. It's a direct ride to Disneyland.
Others

No you would not have sufficient time. You will need a full day for the main park then maybe half a day or three quarters for the studios. As for the three other questions, i dont know, i have always gone there with travel buses and stuff.
Does the metro go through Acton?
