Due to the current Covid-19 pandemic, all regular services and hours may be subject to change. Thus, if the idea is to spend the night in the public area, consider a plan B in case the stay inside the airport is only allowed for those who are close to boarding.
Spending the night at the airport
Doncaster Sheffield airport is open 24 hours a day, so you can spend the night inside the enclosure if you have a flight early in the morning and you do not want to check into a hotel.
Where to rest: As the terminal does not have comfortable places to rest, your best bet will be to lay on the floor. Have blankets or a sleeping bag handy for a better sleep. If you have a bigger budget you can enter the airport's VIP lounge, although it closes at night. There is also a hotel a few minutes from the grounds.
Baggage: You will have to keep your bags with you until check-in time, as there are no left-luggage services.
Eating and drinking: Available options are closed during the night.
Wi-Fi: Access is free.
