[Star Trek] In a game of Hide & Seek, where would the best places to hide on a Galaxy-Class starship be?
gpt
* Inside the holodeck. Create a simple holodeck program that displays an empty holodeck, except a foot or two shorter than the actual holodeck. Then, hide in the empty space.  

* Inside a transporter buffer. Set up a transporter buffer loop and just remain suspended in there for awhile. Great hiding space, potentially fatal.

* In a space suit, with magnetic boots, hanging out on the outside of the hull.

* Out of phase. Look up some engineering files on how to duplicate the effect, then hide out of phase.

* In plain site. Convince the doctor to physically change your appearance, probably even changing gender and species. This seems trivially easy enough to perform and reverse. Simply change your appearance and hide out in plain site.

* In the holodeck, pretending to be an NPC. 

* In the captain's private head. (Maybe you can convince Picard to let you do it as a lark. It's the last place anyone will look!)

* Hanging out in the elementary school in as a younger version of yourself. (Apparently the transporter can be used to make you into a younger version of yourself. Starfleet seems to loathe the concept of immortality, and thus doesn't use this for the obvious medical applications. But you could use it for hide and seek.)

* In a random barrel in a nameless storage bay, preferably one shielded from scans.

* In one of the stasis units in the sick bay morgue. 

* Wesley's bedroom. That's the last place anyone would want to be.
