In 2026, the best strategy is to start with Universal's Islands of Adventure, specifically if you arrive at park opening ("rope drop"). This park contains the most popular high-demand attractions, such as Hagrid’s Magical Creatures Motorbike Adventure and the VelociCoaster, which see their longest wait times in the middle of the day. By finishing the "thrill" side of the resort in the morning, you can then take the Hogwarts Express (if you have a Park-to-Park ticket) over to Universal Studios Florida in the afternoon. Universal Studios generally has more indoor, high-capacity simulator rides (like Revenge of the Mummy and Transformers) that handle afternoon crowds and heat better than the outdoor coasters at Islands of Adventure. Additionally, ending your day at Universal Studios allows you to be closer to the front exit and CityWalk for dinner. However, with the 2025 opening of Epic Universe, you should check if that third park is your true priority, as it currently draws the largest crowds in the entire Universal Orlando Resort.
