Convenient Inns

Install
Use NMM to install. Or place the esp file in your data folder and activate. But really, use a freaking mod manager.

Uninstall
Get all your items out of the chest go to a vanilla interior without the stuff I added. For instance A jarl's long-house or someother place that is NOT and Inn. Save the game. Exit, uninstall the mod using your mod mangager or manually deactivate and delete the esp. Run the game, open your save and continue.

There are no running scripts in the mod. The shared chest uses the vanilla script to shared chests so unistalling should not cause you any issues.
