The Waymarking cache mentioned is in fact just an elaborate multi. Much prefer this one to one of the many mystery caches that have you sat in front of the PC all day instead of out in the fresh air which geocaching was intended for.

Got one today, destination Sungai Udang, Malaysia. Shame it doesn't actually belong to me though. My wife is diabetic so glad to spread the word. Good luck to all their journeys,

Not a problem. I would write a note in the logbook saying that you are on hols. If they are retrieved in the meantime the retriever should have the courtesy to wait until you have logged it into the cache (Hopefully)
