One of the things generations of Italian women, especially my (Italian) mom, taught me about hospitality is to immediately greet your guests with something to drink.  The welcome beverage does not have to be alcoholic (for weddings I STRONGLY suggest waiting on serving alcohol until after the ceremony, it's a long day for people and I've observed guests take advantage of open bars party and party again...).  Self service glass beverage containers can add decor and support the theme to your event.  These three I found online are inexpensive and unique.
