A 6m bell tent can sleep up to 6 - 8 people in sleeping bags perhaps more at a squeeze. A 6 metre size tent will generally fit a family of 4 - 6 for sleeping but will also allow extra space to be comfortable when using the tent during the day . A set-up of this type would consist of 2 x double air bed and 2 x single air beds with some spare room for your luggage.
