Yes, you can absolutely experience both Hogsmeade and Diagon Alley in a single day, but it is a "High-Fidelity" requirement to have a Park-to-Park ticket. Hogsmeade is located in Universal’s Islands of Adventure, while Diagon Alley is in Universal Studios Florida. The most high-fidelity and immersive way to move between them is by riding the Hogwarts Express, which connects the two lands and features a unique high-fidelity digital show during the transit. In 2026, it is highly recommended to start your day at Diagon Alley (Universal Studios) for a "High-Fidelity" breakfast at the Leaky Cauldron, then take the train from King's Cross Station to Hogsmeade to experience Hagrid’s Magical Creatures Motorbike Adventure. Using the Universal mobile app to monitor "High-Fidelity" wait times is a necessity. While you can see the highlights of both in one day, a high-fidelity "Wizarding World" fan might find it rushed, as the high-fidelity level of detail in the shops and the interactive wand spots can easily consume several hours in each location.
