First off let me establish that in my interpretation of Tartarus there are multiple layers and the area we saw with Tirek is just a small portion of such a layer. Also occasionally there are ponies who are allowed to enter Tartarus so long as they follow the rules (which you and your date are fully aware of) and don't try to break anypony out.

So the question is this: If you were to go on a date to Tartarus, what would you want to do?

Free the prisoners and take over the world.

If my date was okay with it.

See some of the biggest monsters possible....from distance. Like looking down at them from a mountain they are half the size of would be cool. Seeing some red glowing lakes of lava and just taking in the creepy nature of the place would be nice...if there is a 'nature' of some sort.

Now you and your date are on a century long "vacation" to the moon. All courtesy of Celestia.
