Hide and seek requires vision. It's not going to be fun at all since a lot their time is to seek hidden items.

A version to play is to get everyone blindfolds, so a scaberger hunt to find selected items that were preplaced.

Hide and seek would be rather difficult to make accessible, since the point of the game is to make it difficult to locate the person. One possibility would be a directional sensor or those lost item tages (like Tile), but it may not have the range, or may be a bit TOO accurate.

One big thing for accessibility is making information accessible. That doesn't necessarily mean braille brochures for everything, but making sure the information is also available in an accessible digital format, which costs much less.

If you do hide and seek in a pitch black room with some gentle obstacles, you will actually have an advantage being blind since you are in your normal living environment while everyone else is deprived of a sense they truly rely on.

But, it know. It's also the kind of idea that sort of promotes the idea of touch-n-feel-ish behaviour, which might be a bit too much of an ice breaker...

Edit: let's add a thought,

There are a lot of party games that deprive you of your vision and force you to do things without seeing. Like sticking both arms into a box and grab something that you can't see and move it through an obstacle course.

And you don't need to see to balance things on your head.
