I would encourage you to have a look at all the different european DLP country sites. Start with disneylandparis.co.uk which is in English, so you get used to the navigation, and then switch to the other country sites, with the help of Google translate.
Each country can have different offers and you might find something that could really make you save a ton on money.
For example a country might have 2 nights free when you book 4, others might have children under 12 free, other free half board and 25% discount, others 40% discount. So depending on the number of nights you want to book and your family composition one offer could be a terrific deal.
Using points is really a terrible deal. If you don't have a use for your points this year, renting them and use the cash to book will always be 2x or 3x times better.
Also all packages sold for DLP include tickets for lenght of stay, so remember to account for that when comparing options.
