DVA on Disney Visa 0% financing?

[Donathius]

So I'm trying to maximize my Disney Visa rewards by paying into a DVA account using my Premier Visa to pay for a cruise next year. I know I get 2% back on the DVA charge, plus a $20 gift card for every $1000 paid with the account. Do DVA charges also get the 0% financing the way Disneyland/World/DCL charges do? I'm paying for the cruise as if it's all cash so no finance charges (pay off the card every month), but if I have to let a charge ride for a month I'm wondering if it would be better to charge the remainder through DVA or put it straight on the Visa.
