I would say no. The problem is, there just aren't any really long days in October (actually September-November). Remember USF closes at 5:30 on any night horror nights is occuring and 6pm or 7pm on other nights. IOA will close at 7pm or earlier most nights. If the parks were open until 9pm, I'd say maybe, but that isn't the case. You will have very low crowds in your favor however.
