To ensure a successful hen's night out, it’s important to plan ahead of time and discuss ideas for activities, set a budget, and identify any restrictions or allergies before the night begins. Additionally, everyone should agree to put away phones during the night in order to get quality time together and respect each other’s boundaries at all times. Finally, having an emergency contact list with names, numbers and addresses of all involved will help ensure that everyone can get home safely at the end of the night.
