I'm wrestling with an ex MRU itin which, preferably, would involve stops in Asia, Oz, South America and Europe. NB I'd also like to break my trip in Europe by about six months.

Is there any way I could do MRU-JNB-HKG-etc-SYD-etc-xHKG-LHR then stopover in London as described, LHR-GRU-SCL-etc. Where I get stuck is trying to get back from South America to MRU without touching N America.

Is there a way to do it, or does this sound like two separate xONEs? Would a Circle Trip of some description be more suitable for either?
