From a UK/EU view its never worth going unless at least a fortnight (14 nights) as the 10hr each way flight, can be a killer, before i got this job it was always a bit of s struggle to get the money together for trips and it was rare to visit every year, now of course with discounts and sometimes free flights, the only problem is not having the time to have off, all leave has been cancelled until at least aug next year maybe even until sept
