A few weeks ago I found a giant holodeck cretaed by Virtual Reality Rooms.

This week I came across the Holodeck Super Store. The difference here is that the holodecks can include objects (such as furniture), whereas other holodecks only change the texture on the surrounding walls.





There's a free demo version that will fit on a First land plot, although it will take up 115 of the 117 allowed objects. They also sell a version for L$500 that lets you purchase additional scenes, and a version for L$9000 that is fully customizeable.
