Although there is no hard and fast rule on how long a high tea should last, always remember that a High Tea experience is meant to be relaxing and unhurried. Allow enough time to enjoy the delicious treats while catching up with family or friends. If you are planning a high tea for a small, social get together, allow approximately 2 hours. To celebrate a special event with friends and family, the recommended length of time to allow for a High Tea is between 3 and 4 hours, depending on your event. As a general rule, for fundraiser high teas, or for high tea parties that the guest of honour is a child or an expecting mum, allow approximately 3 hours.  For other types of events such as Bridal Showers, High Tea Weddings, Hens Parties or Birthdays, the recommended length of time is between 3 to 4 hours. At events lasting longer than 4 hours, the guests might start to experience fatigue. If your guests however, are known for enjoying longer gatherings, then none of the above suggestions apply and you can celebrate to your heart’s content.
