I am not a fan of the snowball method as it doesn't take into account the interest rate on the debts. The Disney CC most likely has a huge interest rate (likely 18 to 20%)compared to a car loan which is usually less than 5%. You would be better served paying the highest interest rate debt first.
Yes, when you do the math, of course it doesn't sound like the most prudent way to get out of debt. Then again, if everyone was doing the math, there wouldn't be
any debt because we wouldn't spend more than we have.
For me the snowball method worked when nothing else would. For several years I've been a reformed spendaholic and I'll never go back. Before discovering the snowball method, I felt like I was paying extra on 5 different debts and not putting a dent in any of them. Snowballing puts all of your focus on the smallest one to get rid of it quickly. Not quite instant gratification but generally an easy 'win' which keeps you motivated to keep going. It's works psychologically, not mathematically. You line them up and it's very systematic to go right down the line.
In the beginning I only had approx. $50/month extra to pay down debt. As each one was paid off, that amount kept growing so that by the time I attacked the bigger ones, the snowball was over $2000/month. If we tried paying those big ones first, only taking little bites, it would have been very discouraging.
In OP's situation, being that close to paying off a car loan (less than 2 full payments) will help immensely to free up that $500/month that could then be applied to other debts. She'll kick them to the curb in no time because by then you are super motivated, you see one success after another, and you're like a grizzly bear in attack mode. It's amazing how it all changes your mindset.
good luck OP! You're so close to the finish line. I know how you're feeling. I used to log in once bills were paid, just to look at it saying Balance: $0. I'd even snap a pic and send it to dh.

As for car buying, I only drive 2.5 miles to the train station and cars stay very low in mileage for me. When it was time to trade in my 2006 (only had like 56000 miles on it) last Jan 2019, I bought one slightly used, 3 yrs old post lease which was still under manuf. warranty and added additional 'certified pre-owned' warranty, saved $17k and it felt brand new to me. First payment was due last March and I paid it off by Halloween. I hated having a car loan again and I don't think I'll ever buy a brand new car again.
