The bathroom has a door for the general area. In addition, a door inside the bedroom/MPR...so they could use it privately too if need be.
The reason for the multipurpose room/bedroom being where it is...that "Egress Window" needs to be inside a bedroom per code (Fire Code) where I live.
The media room...was going for compete darkness/soundproofing...so you could rock out in there and not disturb the rest of the house.
We/I did think about just having it all open except for the bathroom and storage areas.....still could do that...hummmm.
Thanks for all the comments so far...looking forward to hearing more from others too.

I'd say make the bathroom accessible from the general basement area. Also, maybe switch the multi-purpose and workout rooms. I'd want as large of an open space as possible, personally, so I probably wouldn't even have a wall between the workout/arcade/media rooms.
