We have two Disney Visa Reward accounts. For opening the non premier, we got $50 gift card and $50 On board credit for our Apr '13 cruise. Then I opened up the premier and got a $200 gift card. So $250 in gift cards alone. And then we have gotten 1% and 2% back in rewards all year, and I'm not kidding, it paid for at least HALF of our cruise INCLUDING tips and taxes! We are cruising interior deck 7 Magic 4 day in May (almost here!) for $300 pp all said and done thanks to these cards.
And it doesn't stop there. You get 6 months no interest on Disney vacations with it, so it gives you 'free' time to pay it off if you want. You also get 2% (with premier) back in Disney dollars for all the Disney vacation stuff you book, which has added up. We used those rewards to take off of our Disney tickets and got nearly one adult 2 day base pass paid for with rewards. (Was like $175 to put towards the tickets!) And then we use those rewards for dinner when we are at Epcot!
We are definitely over $800+ in incentives and rewards this year. We opened the first card at the end of Mar '13 and its mid Apr' 14, just over a year later, and that is like cruising half off!
Now, I know there are other cards that give you better percentages. HOWEVER, they aren't NEARLy as much fun. If you KNOW you are going to Cruise Disney, you can really get the rewards to add up. We also posted our On Board Expenses early and THEY are 6 months interest free deferred too. So again, time can equal money. (And more rewards! We also get 2% back in Disney rewards for the on board expenses too!) So we get to go on our excursions in peace and relaxation and enjoy Palo knowing that at the end of the cruise, we won't have to deal with them then.
At least this way, it 'forces' (hehe) us to use the rewards on great, and I repeat for us, GREAT vacations.
We also cruise off season and book far ahead of time, or last year, we snatched up a last minute VGT rate and got an incredible deluxe veranda room for $540 pp on 3 day Dream. That trip is what has started the obsession!
About 2 months after our cruise, we got the beloved 10% off voucher code even though we didn't book on board! For us, we got the 10% off anyway AND by then, we had $164 from gift cards/rewards to put on the deposit, so it only cost us $22 pp to book our cruise! I realize you can't always depend on that voucher (so we will hopefully book SOMETHING on this next one for guaranteed 10% off) but boy did we appreciate the pixie dust! Our rooms are over $200 more pp now!
Hope this helps OP!
Ps. the only silver lining I could find in my ridiculous power bills this winter is at least they got us Disney rewards!
