Limo Service Timing: Weddings do not normally go off with military precision. Rent the limousine for at least an extra hour beyond your schedule. Have the limousine come 15-30 minutes early to allow extra time for pictures. Receiving lines take 25 minutes per 100 people and photographers take much more time then you probably figure. It is extremely stressful on everyone if you have left inadequate time for your charter. 

Limousine Service Operators will often do more than 1 wedding in a day. Do not assume you can add time to limo service on your wedding day. Spend a few dollars more so your limousine is guaranteed on time and is not racing away at the conclusion of your trip.

Visit the Limousine operator you are renting from. Ask for references. Insist on a written Limo service contract within 1 week of leaving your deposit. Consider using a major credit card if you are unfamiliar with the limo company you have chosen.

Consider hiring a van or a full sized sedan on addition to the limo to stay at the reception as a "designated driver."
