Finally! The travel bug hotel has now re-opened to visitors and I was able to get in there today, to rescue this little trackable. I understand that the owners are keen to have it returned to them and while getting it to the specific cache it wants to go to (Test Way 2) isn't currently possible (that cache is disabled as it's missing), I will do what I can to help.
Please get in touch with me, so that we can work out a plan for getting it back to you.
