London St Pancras to Disneyland with a direct train takes about 2 hours 45 minutes. However, that service isn't very frequent, so if you have to change trains in Paris, it could take up to 4 hours.
You can't travel directly from Gatwick to Paris by train. You will have to take a train to London St Pancras and then get on another train to Paris. Unbelievably, you can't fly from Gatwick Airport to Paris either.
There is not any direct rail connection between Belfast and France. You will need to travel via London, using ferry service. It will cost you $90 to travel from Belfast to London (ferry and train both), and another $117 to travel to Paris from London via train.
The Eurostar travels between London and Paris, and between London and Brussels. It does not travel between Paris and Geneva.
A train journey from Moscow to London is possible but not directly. As London is on the British Isles, the only connector for trains is across the English Channel to Paris.
The departure time for the train from London to Paris is 10:00 AM.

Plan on the trip from Euro Disney to Paris to be between 35-60 minutes, depending if there is no traffic or if the trains are backed up.
