Guests heading to this Disney Resort will need to make some changes to their travel plans, as a new warning is now in effect, redirecting travel from the parks for those using this mode of transportation.Credit: Gary Campbell-Hall, FlickrNew Disney Resort Travel Warning Now in Effect, Redirecting Travel Plans for ThousandsGetting from central Paris to Disneyland Paris usually requires little strategy. Visitors board an eastbound RER A train, remain aboard until Marne-la-Vallée–Chessy, and emerge beside Disney Village and the entrances to Disneyland Park and Disney Adventure World.For the next two weeks, that familiar one-train journey is unavailable.RER A service is now suspended between Vincennes and Noisy-le-Grand–Mont d’Est from August 8 through August 23, 2026, inclusive. The interruption affects guests traveling between Paris and Disneyland Paris throughout the day, although trains continue operating on both sides of the closed section.Disneyland Paris itself remains open, and Marne-la-Vallée–Chessy station continues receiving RER A trains from the east side of the interruption. The practical problem is in the middle: visitors beginning in Paris must leave the railway, board a replacement bus, and return to the RER A before reaching Disney.Credit: Tom Page, FlickrDisneyland Paris Guests Must Make Two TransfersAccording to the official route published by Île-de-France Mobilités, travelers heading from Paris to Disneyland Paris should take an RER A train toward Boissy-Saint-Léger and exit at Nogent-sur-Marne.From there, they must board a replacement bus to Noisy-le-Grand–Mont d’Est, then transfer back to the RER A for the remaining journey to Marne-la-Vallée–Chessy.That turns one continuous train ride into three separate stages:RER A from Paris to Nogent-sur-Marne.Replacement bus to Noisy-le-Grand–Mont d’Est.RER A to Marne-la-Vallée–Chessy.The same disruption applies in reverse for guests returning to Paris. Transit authorities specifically advise travelers leaving Disneyland Paris in the evening to expect an extended journey and plan their return in advance. The official information currently lists 11:14 p.m. as the final train from Marne-la-Vallée–Chessy toward Paris during the affected period.That detail matters because both Disneyland Paris theme parks moved to 10 p.m. closings beginning August 8. Guests staying through the end of the operating day may have a relatively narrow margin for exiting the park, reaching the station, completing the replacement-bus transfer, and continuing into Paris.Schedules can change, so visitors should confirm their route in the Île-de-France Mobilités or Bonjour RATP journey planner on the day they travel.Credit: Jeremy Thompson, FlickrWhy the RER A Closure Is HappeningThe interruption is part of a scheduled infrastructure project rather than an emergency closure.RATP’s official RER A works calendar confirms that no trains will operate between Vincennes and Noisy-le-Grand–Mont d’Est all day through August 23. Île-de-France Mobilités says the work includes renewing track, switches, sleepers, and ballast along the eastern portion of the line.Nation station presents another complication. RER A trains are not stopping there through August 30 because of separate station-renovation work, including waterproofing and platform improvements. Travelers who ordinarily begin or transfer at Nation must select another departure point.The closure was announced months in advance and previously covered by Inside the Magic. What changed on August 8 is its status: this is no longer a future interruption. It is now in effect.A similar RER A interruption affected Disneyland Paris travel in August 2023, although that project closed a different section between Nation and Val de Fontenay. The recurrence demonstrates why summer visitors should never assume the usual direct route will operate simply because Marne-la-Vallée–Chessy station remains open.Credit: DisneyThe Parks Are Accessible, but the Easy Journey Is GoneThe distinction is important. Disneyland Paris has not lost public transportation, and guests are not stranded without alternatives. The resort’s railway station remains beside the parks—one reason the RER has long been central to planning a Disneyland Paris vacation.Nevertheless, two additional transfers introduce more opportunities for delays, missed connections, and confusion, particularly for international visitors carrying luggage or traveling with young children. Actual conditions will depend on when guests travel; authorities have not promised a fixed end-to-end journey time.Visitors arriving through Charles de Gaulle Airport have other possibilities, including TGV service and airport shuttles. Those options may be worth comparing, especially when airport processing has already become an important Disneyland Paris planning consideration. Some Disney hotel guests may also have access to hotel transportation services connecting with Marne-la-Vallée–Chessy, depending on their accommodations.For most visitors staying in central Paris, however, the official replacement route remains the clearest answer: RER A to Nogent-sur-Marne, bus to Noisy-le-Grand–Mont d’Est, then RER A to Disneyland Paris.The parks have not moved farther from Paris. Until August 23, the journey simply feels that way.The post New: Disney Resort Travel Warning Takes Effect, Interrupting Vacations for Families appeared first on Inside the Magic.
