If it was me, I would do the standard 1 per wall unless you have a specific reason or intent to have more in that area. Maybe put 2, one on either side of the bed for nightstands on that wall like you generally have in a master bedroom. If you are only doing 5 or 6 total outlets then 1 circuit should be enough, but when I saw 8 outlets I figured this was going to be like a hobby room with workbenches or something where more power would be warranted.
