We were in a cat 4, so it should be the same............
I only found two outlets that were accessible. They were at the desk. There is one outlet in the bathroom, but it would only handle a shaver, not a hairdryer. We took an extension cord and it came in very handy because our hairdryer wouldn't fit in the plug near the desk because of the Ground Fault box on the cord.
If you're going to recharge cameras, or need multiple outlets at the same time, I would take an extension cord or power strip.
