Still catching up, but Disney Vacation Account codes as Merchant Disney Vacation Account and does qualify for the $300 Travel. I got the credit immediately on my card and my wife card after it posted. I figured it was worth a try since I think it is pretty easy to request a refund from the DVA account. Used the credits on both cards to fund my Halloween party tickets.
As for good sources of tickets, buy the gift cards from Sam's Club - $150 for $142.9x - about a 4.68% discount or the $500 card from Sam's website is about 5%/ But wait you say, I can get that discount from Target. However, buy it with your Chase Freedom Card during the July - September and October - December and you get 5% back on up to $1,500.00 in purchases from Sam's Club. Convert those points to the Reserve card and you get redemption at 1.5x, so 7.5% return. Fund the Disney Vacation Account for a $20 Gift card on every $1,000.00 in expenses paid by account. NO, you don't get the bonus for requesting a gift card payout.
Potential savings of 5% discount on the card, 7.5% rewards from Chase and $20 per $1,000 from DVA = around a savings of 14.5%
