What I found out when I started to try and level up Final form, was if you go to Twilight Town and go to the White room of the Mansion or the Computer room of the Mansion, you can go easily between the two in final form and defeat the nobodies there. It's faster and easier because you're not just near one save point, but two. While you're still in final form, before you hit 0, go to one of the save points and go to world map WHILE YOU'RE STILL IN FINAL FORM, and it'll recharge your drive guage. Just return to the White or Computer room and repeat as necessary.
