It seems to me, and my first skim-thru that:
1. The district isn't really dissolved. It's "rethemed" (

) into a more modern district. In a model that probably already exists all over Florida as a supercharged Home Owners' Association. The language, I would guess, is a copy-paste from existing Special Districts. It's duties are basically the same as any district's board/council. The language is almost exclusively about the infrastructure.
2. With the district not really dissolved, then the bond issue is moot. The new district just takes up the role of responsibility of all current and any new bonds. Disney still pays county tax and still pays extra tax to the revised district. So, there is no issue of the counties being stuck with RFID's bond bills.
3. The really big difference from other districts is the governor with approval from the senate chooses the board. We'll see if that passes FL constitutional law.
4. The new board can use their powers to make life hell for Disney. (As any council or even state legislature could for their constituents). The language of the bill provides due process for input to anything the board does, the ability to lodge complaints, and the freedom for everyone to sue everyone else. I'm surprised there is no forced arbitration.
5. The board members have a lot on their plate and no compensation except a per diem. I don't know who would agree to being on the board.
6. The option to go to Federal Court over a 2nd Amendment claim is still on the table.
