My fiancé and I really would like to have our wedding in his parent's backyard but the area is grassy with quite a slope. Is it possible to have a tent/dance floor setup on this kind of surface? Has anyone else experienced something similar? How did you deal with the slope? Is there a way to put something under the floor to even it out a bit? Are vendors able to do this? We're also on a pretty tight budget so if it would be too expensive to do this, please let me know.
