Fair enough, good point.

Oh I've tried several. Spatial (which is now more general metaverse and less businessy, sadly), Arthur. Immersed. And now we're using MS Mesh. Mesh kinda sucks (it works, but you can't do anything and even the meeting host has no control over the instancing). But it's free with O365.
Mesh is basically a rebadged AltSpaceVR by the way, but with most of the features removed, curiously.
I'm kinda curious which one you're working on though :) I know there's more than the above but I haven't tried them. The biggest problem of all of them though is the usecase. The why. Even though Mesh is free now, I have a really hard time justifying why to actually deploy it.
The whole convention thing is not really worth it IMO, and not many sites bother with WebXR anymore. Personally I'm a huge VR enthusiast and just hanging out is a perfectly good reason for me but I have bosses that are a lot more critical :)
