We love DCL cruises and now prefer them to visiting the parks. Our most recent trip we spent a couple nights at WDW resorts before and after the cruise, but mostly just relaxed and enjoyed the resort - we only visited Typhoon Lagoon and a MVMCP.
Depending on what cruise and what hotel, it is possible for a WDW stay to cost more or less than a DCL cruise. THere are many factors to consider. Our recent stay at WDW, some of the hotel nights the hotel cost alone was more than the per night cost of our cruise. But we made the choice: deluxe hotel, rack rate because no discounts were available. Part of why we only stayed a couple nights ;-)
DCL has similar functional "seasons" in terms of price, much like the hotels do (though not as formal as the hotels do: the hotels actually have a published schedule of formal named "seasons" with dates attached; if DCL has something similar I haven't ever seen it published, just price variability corresponding to various times of the year) -- so over holidays and school breaks will be much more expensive as a general rule. Also, some cruises (e.g. Alaska) are just always going to be more expensive than others. Finally, with DCL, almost always the price for a given cruise is cheapest on opening day (when the cruise first becomes available to book) and possibly soon after, and then at some point starts to increase and usually just keeps going up in price.
OP, an option to consider could be a combination trip: some days at WDW and a shorter DCL cruise, such as a 3 or 4 night DCL combined with a few days at DCL to make up your week.
Also, I recomend a good guidebook, such as the Passporters cruise guide, to help get a good overview of DCL cruises. Much of the info can also be found online across various sites, but I find having it in one place can be useful, especiall when planning your first cruise and as a quick reference for future cruises after that. I then use it as a starting point for further research online. Also, the DCL website itself has plenty of info, including the ability to cost out cruises -- so you can get a good idea of how much the cost will be for various options.
