Experience grid-wide Teleport door

connect rooms located in different sims via a door.
This is more realistic than using space age looking teleporters.

Just edit the contents, delete the landmark and drop your own landmark in it.

Note: you need to own the land to be able to add the experience required. If not, get the inter-sim teleport door, it is a little slower to teleport but it works all the time.
Also, you need to have basic object editing skills to delete and add a landmark inside the door.
I stand behind my work. If any issue, leave me a notecard before you decide to leave a bad review. I would gladly help you.
