Here's a fun little gift for the Stag Party but it may also help you out come the end of the evening if you are partying away from home.
Jot the name of your hotel and a contact phone number on the Drunk and Disorderly label and attach to your clothing. That way you will be sure to find your way back to the group.
It'll be a conversation starter throughout the evening and even when you enjoy your drink responsibly it's sometimes hard to remember the name of the place you are staying. I mean, who is honestly listening when the evening's plans are given out?
