The simple answer is yes. If you have arranged a direct cremation then a private or more public ceremony can be held at a time and place of your choosing. This could be near the date of the cremation, or weeks, or months later. A ceremony can be held in an intimate setting, such as a garden, a house, or other meeting space, or in a larger setting, either indoors or outdoors. The larger the gathering the more you will need to consider facilities and amenities and if permission is required.
