Hi,
How long are the lines to buy tickets ? We are planning to be there in 2 days at about 10am. Any advice is appreciated!
Why don't you purchase them online? You can get them printed at home and this way can save you from waiting. ;)
They are also cheaper by buying in advance :)
Prices on the gate are usually the most expensive.
As you are near to your date of visit, if you order online then you will need print at home tickets, as actual park ticket won't get to you in time.
Some of the supermarkets in France sell Disney tickets, also some of the Dover - Calais ferries do, although I don't know how their prices compare or if these are suitable for you.
