Make It a Vacation
The RSVP cards have started pouring in, and your nuptials have made a lot of people's summer to-do lists. Why not make your wedding only one part of a fun vacation for them? They might want to take advantage of the warm weather to see some sights in your city. Make it easy for them and do some legwork ahead of time. Put together a welcome kit for your out-of-towners: fill up a gift bag with a local magazine, a transit or road map, and a list of your favorite al fresco dining recommendations.
You also might want to add information on activities and attractions geared toward your guests' interests. Got a few kids coming? Tell them (and their parents) about a cool playground or children's museum -- unless you perhaps want them saving up all that energy for your wedding. Is your uncle a big baseball fan? See if the local team's in town. Tailor your recommendations and give your guests a wedding weekend to remember.
