Yes, Universal Express passes can and do sell out, especially during peak seasons like Spring Break, the December holidays, and "Halloween Horror Nights." In 2026, with the opening of Epic Universe in Orlando, demand for Express passes across all Universal parks has reached an all-time high. Because the parks want to keep the "Express" lines short, they limit the number of passes sold each day. On particularly busy days, the price for a pass can also skyrocket due to dynamic pricing, sometimes costing more than the park admission ticket itself. To guarantee you get one at the best price, it is highly recommended to buy your Express pass online at least several weeks in advance. Remember, if you stay at a "Premier" level Universal hotel, these passes are often included for free as a perk of your stay.
