Those whom work hard probably go oversea in June and Dec when School holiday start.
Those work smart will go oversea to enjoy life every month.
I go oversea 1-2 times a month; and I am holding 10 prepaid air tickets till June 2015.
Hence how often you go oversea depend on how deep your pocket is and how you make your money.
Those whom work in JB go oversea everyday..... but does that count?
