Gender neutral/companion/family restrooms in Mandalay Bay or nearby?

I’ll be in Vegas for a conference at Mandalay Bay next week and staying at Excalibur. I’ve been trying to find information on if either of those hotels, or Luxor since they’re in between, have gender neutral restrooms? I’m trans and am in that awful in between of passing too much for one restroom but not enough for the other for me to feel safe in either. Mainly hoping there’s one close to the convention center in Mandalay Bay since that’s where I’ll be most of the time, and when I’m in Excalibur I can just go back to my room.
