Yes, showers are included. Think of the lodgings as an upscale hotel from the late 19th century which has been updated to accommodate metahumans, but not technologically. There is electricity, but no trids and few electronics other than the security measures and a Renraku Manservant drone.
You are free to use your commlinks, but the wireless functionality won't work outside of the room you are in. So you could slot chips or use your commlink for an alarm clock, but not to send messages to each other unless you're in the same room.
There is plenty of hot water. Soap, shampoo, and shaving products are provided, as well as towels, robes, etc.
At this point we can either fast-forward a couple hours or we can meet up for a discussion of next steps. I figure Mal/Ohanzee will make the call, although others can chime in ICly or OOCly.
