Well it won’t have A/C.FWIW, i've lived in Alabama for 40 years now and have been to Orlando in the summer. There's no way I would get in any enclosed vehicle or structure without air conditioning when its over 70 degrees! Its misery here to get in a vehicle in the summer time until the air conditioner kicks in, or when your power goes out in the summer. The heat and humidity can be brutal.
And as for non A/C ventilation, all you are doing is moving hot air inside.
I don't find it silly at all, and I keep wondering what Disney was thinking to not include air conditioning.
I honestly don’t think it’s that big of a deal.
