No, I'm not suggesting that at all.
I'm saying, as far as I know, Disney does not pay property taxes on property they don't own so roads owned and maintained by RCID, I do not believe Disney is paying property taxes for. Those giant parking garages next to Disney Springs? As far as I know, Disney isn't paying property taxes for them, either.
Westshore Mall in Tampa has a parking garage. I'm pretty sure they pay property taxes for it... because they own it.
I'm pretty sure Disney hadn't had RCIP, they'd own their Disney Springs parking garages and the land they sit on, too.
