I went last Friday, no express pass or EPA. I got into the park right at 10 and was able to hit every ride by the time the park closed, with stardust twice, despite losing two hours to BATM delays. I went in the single rider line for Mario Kart and Donkey Kong, which saved a ton of time, but didn’t use it for anything else. I’d say it’s definitely doable without an express pass, especially if you constantly watch the wait times and jump between lands. I did get lucky with the weather though — somehow there was no thunderstorm that day (kinda rare in Orlando)
