A: No way are you obligated to pay for your guests' travel costs. But you are responsible for helping make the trip more affordable. Look into group rates at local hotels—it's easy to score a discount if you're promising that a block of rooms will be booked. If some of his family members are really financially strapped, ask local friends and family if they can host a guest or two. And try to schedule a few parties, tours or other entertainment, so that guests won't have to spring for as many meals or diversions.
