I'm in the same boat of having to have everything out of the venue out by 1am.
The venue coordinator actually recommended we park a u-haul in the parking lot for all decor since there is a quick tear down timeframe. That way we don't have to sort any rentals the night of. And we don't have to pick up the u-haul until 10 the next day so there's plenty of time in the morning to figure it out.
We're thinking of asking a few of our friends and family who don't drink as much to help with the teardown so we aren't doing it ourselves and we'll be able to rely on them at the end of the night.
As easy as it was to set up, its harder to break down.
Get some family members or friends to help out with areas they can arrange as needed and right into your room or car. Make a list of what needs to be done and organize it by tackling what would take longer to the shortest. Hubby can bring the car around and load it up if it helps.
I had to get the vendors out and the restaurant cleaned up by 1:30am after our wedding function too. This is what was done by having family coming up asking how they could help.
When it came to my sisters- they told all of the wedding party they were expected to help with cleanup at the end of the night and take down of all items and the parents of both sides. This is what happened at 12:30- we all tore it down and stuffed the vehicles- if you have a lot of stuff I would suggest a trailer and to leave there locked at night if you are worried about people having to many drinks to drive it.
At my FSIL’s wedding, her parents drove to the hall so we loaded up extra centrepieces left behind, money box and anything else leftover into the car and took it home with us.
for my venue, we will try to do the same thing as well. I may even talk to my venue coordinator to ask if I can’t fit everything into the limo, if I can keep it in the hall until 7am or so and come to retrieve it in the morning. I don’t see why this would be an issue if I retrieved it well before any events the next day.
