Every week we ask some of our top wedding pros for advice about wedding planning. This week's question:

"What's the number one thing brides and grooms forget when planning their wedding?"

Here are some of our favorite answers:

Jim Miller of Bluegrass Sound Band (Marietta, Georgia):

To have a backup indoor plan for an outdoor wedding.

Jeff Tucker of On the Beach (Toledo, Ohio):

To carefully script the ceremony and be sure to include music and music cues in the script.

John Marsh of Legacy Music (Atlanta, Georgia):

To feed the band!

Dave Edwards, Piano Player (Dallas, Texas):

They often forget that while a facility may have a piano in the chapel, it may not have one in the reception hall.

Sean Zurbrick of Next Exit (Dublin, Ohio):

Timing! They underestimate the time needed after the ceremony for pictures. They also underestimate the time for dinner.

Lisa Perkins of The Lisa Perkins Band:

To make sure there's enough power at the venue for the DJ or band.
