No one from my FI's family will be at our wedding either. His dad has a hard time getting around (but can afford to go!), his brother and sister can't afford to go. He's not even bothering to invite anyone because of the cost - all his friends and family are in Cali. Flights are outrageous from Cali to St. Thomas
The only person I wish was there is his dad, but FI won't give him the details about the wedding. He said he wouldn't be able to enjoy it because he'd be too worried about his dad the whole time.
