From what I understand is if you buy through disney you can. I recently bought SSR and put it on my Disney visa and then paid it off. I checked and the rewards are there. I guess you need to contact disney & see what they have available.
If you charge the entire amount, are there still any 6 mos. 0% interest promos running? That might allow for a higher number of points to be purchased if you could pay it off over six months vs. your statement due date.
You can charge the whole thing if you want. The only way you can get 0% on the whole amount is if you just openend the card. That is the promo they are offering right now. If you go to dvcmember site you can click on the visa ad and see the rewards. Hope this helps. We already have a card opened so we can only get 0% on the down payment of 2500. That is how my guide explained it to me.
