DVC.
I associate DVC with kids sleeping in a different room and a lot of space. A cruise ship with a tiny cabin. Perhaps in a suite I'd feel differently.
I can enjoy almost everything I can enjoy on a cruise ship at Disney. Good Food. Pools. Sunshine. I have a lot more flexibility - if I feel like sitting by the pool, I can. If I want to go to the parks I can.
Cruising is very relaxing, but fourteen days is a long time to be on a ship! I'd go stir crazy. You get off the ship on their schedule. The pools aren't nearly big enough to keep everyone happy for two weeks.
