How cheap can disneyland paris be done?

Hi

I really want to go to Disneyland Paris either late this year, early next year for 4 days/3 nights. I have search on the disneyland website etc and obviously this is very expensive.

How cheap have any of you done it, i.e using easyjet/ryan air, driving down, staying in cheap accomodation as opposed to disneyland hotels.

Surely it can be done quite reasonably?

Just thought i'd ask before i spend the next few weeks trawling the websites.

There would be 6 of us, 4 adults and 2 children (one 5 and one 8)

Thanks in advance x
