The old bait and switch. You want to make sure that if you see a specific limo you want, you can get that exact Limo on the day of your wedding. So many times, I see companies bait and switch their clients. They promise you the world, and then the day of your wedding, you get whatever they send you, and then they say, we "upgraded." This is one of the most frustrating things that can happen during a wedding day. You want to make sure that you have it in writing that you ordered a particular limo and that if they send anything but that Limo, you will get some form of compensation.
This is something I see in almost half the weddings we photograph. These limo companies abuse these cars, and because of that, they send out limos where the air conditioning does not work, the window won't roll down, the moon roof is broken, or the doors do not open from the inside. You want to make sure that you have it in writing that the Limo you order for the most important day of your life is in 100% working order.
I know it seems like a weird question, but for some reason, many Limo companies like to get paid the day of the wedding. The last thing you want on your mind is how much money to bring with you to the Church to pay for a particular vendor. There are many ways to relieve stress on your wedding day, and this is one of the easiest. Pay your vendors before the wedding; this way, money is the last thing on your mind.
This is important for many reasons. One of the most important reasons is, you have very little say in how things play out during your wedding day. If hair and makeup run 45 minutes late, then the Church runs 45 minutes late; you just lost an hour and a half of your wedding day. You want to make sure that your Limo driver does not have any prior obligations. Such as picking up another bride and groom after he drops you off. This is important because having options is one of the keys to being stress-free. You need flexibility in your vendors. You want to be able to know, going in, if anything runs late, my Limo is going to cost me X more.
Random question, right? I know, but the truth is, many times, when you arrive at the Church, most people have no idea what they are doing. They don't have anyone to organize the guests, telling them where to go, where to line up, when to walk down the aisle, etc. Most times, the Limo driver will help with this. But make sure that it is in the limo driver's contractual duties to do help in this way. If it is, great, you are covered; if it is not, then that is something that you are going to have to work out with either your day-of coordinator or someone at the Church before your wedding. I have personally seen weddings that were supposed to start on time run 30 minutes + late because no one knew who was in charge at the Church, and they couldn't figure out what to do and how to get started—having a plan before the wedding is the best way to keep things running smooth and stress-free.
