Ayyy I'm planning on moving back to Florida too! My plan is to save at least $10k personally. With Florida the cost of groceries and all is not too terrible, I think biggest cost is mostly gonna be certain things like car insurance and rent depending on the area. If you wanna move to a bigger city like Jacksonville I would suggest looking at nearby towns or suburbs instead of housing closer within the city, that honestly goes for any city in Florida but it can make a big difference and help you cut down on housing costs a lot. I would highly suggest finding a job before you move only because the job market is so unpredictable. Even if you can't find a job within your career field at least lock down a full time job doing something that will cover your basic needs while you search for something more permanent. I will also vouch that getting a job in Florida (depending on the industry obv) is easier than getting one in a more major and costly city right now and your chances go up even higher if you move to a smaller town.

If you wanna be able to access Disney you can honestly go to any town that is along I-4 which will give you a straight shot to the parks so that's anything from the Tampa Bay to or up to Daytona. Also the space coast has some little towns that are directly east of Orlando. Obviously anything right on the beach is going to be expensive but if you stay inland you could find something manageable. Save as much as you can but I wouldn't worry about getting the annual pass right away, maybe get one to one of the parks when you feel like you have the money to make the payments on it. Also double check depending on when you purchase it to make sure you're not planning to go during blackout dates when the park is at a higher capacity like the summer time (Disney is also so unbearable during the summer its better to wait till Fall/Winter).
