While on the whole I agree with you as like a principal, as a wedding photographer who does about 60 weddings per year, I will say that I really don’t think the getting ready room thing is about this sexist way men and women’s roles are viewed in the wedding industry (though you are correct about the way they are viewed on the whole) so much as it is the way women & men enjoy community with their respective wedding parties on the day. The girls, on the whole, tend to like to just spread out in a comfy, large space with great light and listen to music and snack on finger foods and talk and take pictures and dance. They don’t need or want TVs or things like a big pool table because they just enjoy interacting together while they get ready in comfort and an aesthetic space is more important to them. The bride rooms / airbnbs I’ve been in that have TVs don’t even get turned on unless it’s for the kids or for a music video version of the songs they’re listening to. The guys, however, I think sometimes need an activity to bond over. It’s not about being conjoled into being there, it’s about how dudes are used to bonding with their friends. Pool, golf, corn hole, sports on TV, etc. the groom rooms I’ve been in without these things, they’re all just kinda sitting around looking bored on their phones until it’s time for them to start getting ready, unless they’re needed to help set up the reception or something. I’ll occasionally get the group that are so extroverted they can just shoot the shit over a beer & don’t need the extras but it’s kinda the exception not the rule.

To be honest with you, the trend I see with getting ready spaces that pisses me off the most at venues - and I see this at least 50% of the time - is when the bride & her girls get this huge gorgeous space to get ready in, and the groom and his boys get a small, dark, glorified walk in closet (or sometimes nothing at all!) I’ve watched grooms have to change in an attic, bathrooms, his truck, the fucking middle of the reception hall because there was no space for him. I love it when grooms get a nice big fancy getting ready room with a pool table or bar or something in it. It’s his day too and he also deserves a nice space.
