When you are putting together welcome gift bags, consider the following ideas:
An itinerary that your guests can refer to.
Information on things to do in the city or town, including restaurants to visit.
Thank you notes personalised for each person in attendance.
Customised gifts such as mugs, towels and umbrellas with branding such as your logo or recipient names.
Local soaps, snacks and drinks.
Hangover kits.
Sleep masks or other practical items dependent on the event.
