I agree with other posters. The Disney premier card is good for some people, but not the best option for everyone. I've seen many people say that the airline credit cards offer much more beneficial rewards than the Disney cards, but we're road trip people and don't really fly anywhere, so those cards don't make sense for us. YMMV. I know there are also other cards that offer cash back rewards at a higher percent than the Disney cards. I prefer to keep the Disney card for now because I like that the rewards are focused to Disney trips.
We use the Disney Premier card for everything because the 2% categories (gas, restaurants, and groceries) are the things we use that card for the most. We also have a Chase Freedom card for whatever the 5% bonus category is that quarter. This quarter it's grocery stores, so I'm not using the Disney card for groceries right now because the rewards are better on the Chase Freedom card. I use the rewards dollars from both cards for our Disney trips.
For our trip last June, we had accrued $3700 in Disney rewards and $500 in Chase Freedom rewards (which I take as a statement credit and used the card for hotels on the drive to and from Disney). Those rewards were earned over 4 years because we didn't have a trip in 2020. But we typically accrue about $2,000-$2500 between trips (going every other year). I already have about $1200 accrued between the 2 cards since June.
The Disney Visa (free or premier) gives you 6 months free financing if you use the card to book/pay for your Disney trip. That's not a benefit we use, but I know that's very useful for some families. The Disney Premier card allows you to use rewards for airline tickets (via a statement credit). There is also the 10% discount on food and merchandise purchases over $50 at Disney World. That usually saves us anywhere between $50-75/trip so that factors into our decision to use the Disney Visa for rewards as well. Plus they have really fun card designs that cashiers comment on all the time.
