Yes, Universal Express Passes can and do sell out, particularly during peak travel seasons like Spring Break, summer holidays, and the weeks surrounding Christmas and New Year's. Unlike standard park tickets, Universal limits the number of Express Passes sold each day to ensure that the "Express" lines stay significantly shorter than the standby lines. As of 2026, with the opening of the massive new Epic Universe park in Orlando, demand for skip-the-line access is at an all-time high. Prices for these passes are dynamic, meaning they get more expensive as the park gets busier and the remaining inventory decreases. To guarantee access and secure a lower price, it is highly recommended to purchase your Express Pass online as soon as you book your trip. Alternatively, staying at a Universal Premier Category Hotel (such as Portofino Bay, Royal Pacific, or Hard Rock) includes complimentary Unlimited Express Passes for all guests, which is often a more cost-effective way to get the benefit during high-demand periods.
