Why winter changes the planning
In summer the tent protects from sun and rain; in winter it must also keep the heat in and stand up to snow. Four things join the usual list: sized heating, lighting designed for night, flooring that insulates from damp, and a procedure for snow or wind.
Night falls early in winter: the ceremony and cocktail often take place in artificial light. Lighting is no longer a decorative detail, it is part of the organisation.
