It will be long, about 4 hours for your child doing something for about 4 min.
It will cost you cash, yes you paid her fees, next up yours. Admission, Potential snacks, drinks, trinkets, tee shirts and leos. We don't usually buy unless its states and she places or regionals, then its usually a tee.
Parking will likely be a hassle. Don't arrive too early but certainly don't be late. Our coach expects our gymmies there about 15 min before report time.
Get a seat where awards will be, unless its in a different room. Our gym sits in the same general area. And we wander, so the video/photo members (my husband does video, I do photos) get good shots. One your kid goes, get out of the way filming wise. And be aware when walking of other folks with cameras because they too are filming. I learned to edit video when my husband let a few choice words sneak out when some one walked across the camera as our kid was doing beam.
The awards will seem to go on forever (to me any how), with mulitple age groups.
Lots of chatter and its not all good.
Best advice I was ever given in a what to expect memo by our old gym. Remember nearly everyone in the audience has a gymmie they care a lot about competing. Please watch what you say.
If you pack her a snack, make it easy to eat and not messy. I try to not send nuts, because you never know if there is a kid with nut allergies. Actually I have gotten a bit lazy and tend to spring for something at the meet.
Make sure your devices are charged up and bring a charger, just in case.
My thing is if there is a professional photographer, buy the photos. They get much better shots because they are allowed on the floor. I do this usually once a season. I only buy the digital images. I photoshop my own collages, way cheaper then buying theirs.
Thats all that comes to mind at the moment.
