This is how I look at it, too. I recently chose between spending Easter weekend on a 3-night Dream cruise or at WDW with a 4-night stay in a standard room at Animal Kingdom Lodge. I chose WDW since we just cruised the Fantasy in December, and I want us to see Wishes & La Nouba one last time before they're gone forever.
Between lodging, food and 3-day one park per day passes for only 2 people, the full-price Dream cruise in a verandah stateroom would have been significantly cheaper than WDW, even though I got the AKL resort room with a 25% discount. Yes, the cruise is one less night, but still...
Disney is raising their prices across the board- it seems to be currently even worse at the resorts than it is for the cruise line. Given the higher WDW crowds & less reasonable prices for even their cheapest deluxe rooms, I'm leaning more towards DCL than WDW these days. I also like that DCL takes you to new places, which WDW obviously can't do.
