No, you generally cannot take a kids' wagon or stroller wagon into Disneyland as of March 2026. Disney’s official policy strictly prohibits "wagons" and "stroller wagons" (regardless of the brand, such as Keenz or WonderFold) in all of its theme parks. This rule was implemented to keep the narrow walkways and busy plazas of the parks clear and safe for all guests. The only exception to this rule is for medically necessary wagons, but this requires a specific evaluation by Disney's Guest Relations team upon arrival; even then, the wagon must be tagged with a special medical identifier. For standard families, the maximum allowed stroller size is 31" (79 cm) x 52" (132 cm). If you arrive with a wagon, security will turn you away at the entrance. To avoid this, most families in 2026 either bring a compliant double-stroller or use the daily rental services available at the Disneyland Resort, which cost approximately $15 per day for a single and $31 for a double, ensuring a "hassle-free" entry into the park.
