This is a travel bug / coin hotel. The main idea of a travel bug hotel is to help travel bugs do what they are meant to do, and that is travel. This is not a prison for the bugs, so there is no need for a one for one swap. By all means visit this cache more than once to assist the bugs to keep moving.
