It would depend on where you live. If you are renting the door or stand would be the way to go. The stand seems to work good, you just have to find a way to store it. Not sure how the door mount mounts,but there should be a clip to remove the swing from the mount.
Now if you live in a house the best would be to mount it to the ceiling. You can leave the eye bolt in the ceiling and just store the swing when not in use. Just be sure that you mount it to the ceiling joist, I might even get up there and add some more reinforcement, just in case.
