Okay, first of all, I cannot exaggerate enough how important it is to trust your wedding planner (me). After all, you are entrusting your big day to a stranger. After meeting me, all that goes away and we become like family. Nonetheless, you have to trust your wedding planner to come through with all her promises. It's important that you fully read your contract and you and your planner are on the same page (no pun intended).
If it is an beach or outdoor wedding, your planner will make suggestions for a plan B. Nowadays, mother nature is all over the place. At best, your wedding will be perfect (which is most of the time).
Back to the trust issue. Rely on your planner to help you through the planning process as she can guide you from the very beginning to end. As your planner, I will discuss the weather, venues, accommodations, color palette, wedding dress options, flowers, reception, and even your bridal emergency kit.
To wrap it up, from the first communication to your wedding day, my work is not done until I walk with a smile on my face.
