Our friends had a back yard wedding; they have a “medium” back yard (meaning that to a city dweller like myself, it feels pretty big, but it’s not even a half acre so it’s really not that big) that ends in a privacy fence to the next neighbor’s yard. So the view back there was nothing to write home about, although their yard was (and always has been) gorgeous. They spend a lot of time in their flower garden, have a koi pond, etc. So it was a nice space. They brought in a tent and I’d guess it was about 60 people.
Everyone enjoyed the day, and thought it was a lovely ceremony and reception; I don’t think anyone felt “put off” that it was so casual.
The things the couple complained about though:
-Apparently dealing with the port-o-potties was a nightmare, even if they went for the more expensive “mobile bathroom” model. They had to get a permit from the city to park it in their driveway and had a lot of logistical issues with the delivery company. There were also some challenges with the stairs for their older guests
-Their lawn was shredded by ladies in high heels and it took pretty much the rest of the summer for them to get it back in order. This may or may not be a big deal to you (or the lawn-owner) depending on how emotionally attached you are to the lawn
-Trash and recycling disposal was a huge issue, as they simply did not have enough trashcans for all the trash, even after borrowing from half their neighbors, and in the city where they live, you can get a fine for putting trash out at the curb in just a trashbag and no trashcan (it attracts critters)
-They had no proper Plan B in the event of rain, and while they did have a tent, it wouldn’t have stood up to even a halfway strong rain shower. They did end up with a gorgeous, non-rainy day, but they both stressed endlessly over that
Also, parking was a big issue for them. They had talked with all their neighbors in advance so as to not cause any neighbor drama, but still their street wasn’t big enough to fit all those cars (this is your generic suburban neighborhood) especially with the port-o-potty truck, caterer van and etc. They also had a very hard time relaxing because they (actually most of the adults) were constantly on the lookout for little kids who escaped the back yard as we had a couple of the kids run into the street– no one got hurt, and there weren’t even any close calls, but any adult who sees a kid dart out into the street gets really worried, and that was a big issue all day long.
