Gender reveal thoughts?

M
So I'm trying to plan our gender reveal for next month. We live in WY so it's freezing and outdoor is not an option. I'm curious to know if gender reveals are more so a family and close friends type of thing or to invite a crap ton of people. The only down fall to inviting a lot of people would be I would have to rent a large space for the afternoon to throw the party.

I'm leaning more towards a small one at our home, but just wanted ideas and opinions! Thanks!
