It's an add-on fee based strictly on availability as well as to whose primary benefit the attendance is. Most rehearsals are in direct conflict with another event or personal schedule therefore unless brought up specifically in conversation, this topic in not addressed.
The ones I have attended are nearly all chaotic and a waste of minimally two hours which includes drive time and thumb twiddling stand around time while some 25 year old clueless house coordinator flexes inept muscle. A couple of times, a polite "step in and take over" was obviously needed, but nonetheless did not win any friends with the facility person. Possesive and protective some of those wedding Nazis be.
If I can't lay the track, I ain't drivin' the train. LOL!!
If I do a ceremony, I do the rehearsal and it's added in as part of my fee for ceremony service which includes the day before rehearsal, and day of sound. I haven't run into the issues in my neck of the woods that my esteemed colleague Cap has, and frankly most coordinators in my area are happy to let me lay the tracks, and drive the train. Ok by me.
Capper, honest, I haven't. That doesn't mean that there are not Godzilla bridal coordinators running amock in North Cackalacky. I am positive that there are. A lot of my couples do not hire coordinators when they discover that my wife and I do that. So truly, we probably avoid the problem altogether via our marketing. And the one's I've actually run into were clueless, and left it to me to run the ceremony rehearsal, after using that Southern charm on them(spelled 2x4, lol) and giving them a bride completed planner to follow along with
I've just been Realllly lucky. Now it's time to bang my head on some wood.
Since most of my events are incredibly close to me (seriously, <5 miles away), I offer it as a value-added feature when I close with a bride and groom. It's also a chance to make nice with a coordinator for a future referral.
I do ceremonies, but I do not attend rehearsal.
Most of my weddings are short and sweet (15 to 20 minutes) and only need a few songs...
so it's not anything I cannot figure out when I talk to the client on the phone.
