Any alternative ideas for a dance floor?

If this venue hosts weddings often, the venue should be able to make recommendations based on past events.

I had this same issue at a hotel I worked at once. In the end, we set up poles (in stands) the type you use to create pipe and drape and then we strung string lights across it. We started in one corner and zig-zagged back and forth over the dance floor. You could probably find pipe and drape pieces for rent.

Welcome to the community Casey! I really like the idea of defining your dancefloor with lights. I think it would look really pretty and there would certainly be no confusion as to where your dancefloor is!

Is your dancefloor indoors?
