Space Mountain – Space Mountain's single rider line entrance is not located at the main entrance of the ride, it's located at the exit. Head to Space Mountain's exit area, which is past the left side of The Star Trader shop, and look for signs pointing to the single rider queue.

As of early 2026, Space Mountain at Magic Kingdom (Disney World) has begun testing a dedicated Single Rider line, though it is not yet a permanent, guaranteed feature. In late January 2026, the ride briefly opened a separate queue that utilizes the "Omega" side of the loading area to fill empty seats, potentially shaving 10 to 30 minutes off the standard wait time. For most of its history, Space Mountain lacked this option, requiring solo travelers to wait in the main standby line. At Disneyland in California, Space Mountain occasionally offers a single rider option via the exit, but it is often suspended during peak periods to prevent overcrowding. If you are visiting in 2026, the best "pro-tip" is to check the official Disney app's "Single Rider Option" icon; if it’s active, you can save significant time, though be prepared to bypass the immersive "Starport Seven-Five" themed queue and be separated from your party at the loading dock.
