You may not realize this is a worldwide forum. As my name shows, I’m in Missouri. I’m not sure if there are any Pennsylvania members in this group.

And it’s hard to give generic advice without a picture. Do you have a feel for whether there might be snow on the ground in two weeks?

Invite enough people and no one will be able to see the ground. Seriously.

Talk to a wedding planner - you could bring in a dance floor and dining area.

The party is outside or you just need to do something with your backyard?

At this time of year not only is it difficult to hire a landscaper, it will be difficult to get material as well.

Thank you. Weather has been mid to high 50s and looking out to the date, doesnt seem to be likelihood of snow.

The party is outside but seems like we are just going to have to forewarn people that we are in process if updating and if they are offended by messiness, dont come :)

I'm sorry but one does not plan outdoor parties for the end of November even in my very mild winter climate!! Unless in a covered and heated marquee. And those usually come with floors.

If not, I wouldn't be concerned about the bumpiness...your guests will be too uncomfortable to notice.
