Advice Needed for an upcoming event

I'm doing a small little gathering event with about 50 to 70 people. The space where I'll be doing the main shots at is an open floor, think of a dance floor at a club. low light and people dressed with funny hats and or maybe costumes. it's a birthday party. I don't believe I'll be able to use flash. I'm not sure yet so it's not part of my planning for it. But, I was thinking it would be fun to take wide angle / fisheye style journalistic photos. where 3 feet you could see distortion but at 5 feet the distortion would be minimal to the ends of the frame.

I have a canon 80d and a fujifilm x t20 I could use.

I found some sample images I like but they're using a Canon EF 8-15mm f/4L Fisheye USM Ultra-Wide Zoom Lens. with an f4 I don't think the images will turn out well in such low light. and I don't know that I want to spend that much money for a lens I'll only use a few times.

I was thinking the Meike 7.5mm F/2.8 Large Aperture Ultra Wide Circular fisheye Lens Manual Focus might be the best thing to use. bummed about no autofocus but its okay, I can do zone focusing.

so, I'm really thinking out loud. Do you think the Meike might work for what I'd like to do? or do you have any recommendations or different points you think I should consider?

Here's an example of the type of fisheye images I'd like to recreate. the photographer uses the canon lens I mention above. Tips on using a fish-eye lens - Tangents https://share.google/22Cn8a7tFTaX67hui
