Planning to Visit MACAU AND HONG KONG

Where are you flying out on May 12th? Anyway, since u wanna stay longer in Macao, I'd suggest you visit Hk first. Based on your demand, here is the general itinerary for your reference:
May 9: Go to Tsim Sha Tui - Victoria Bay and experience the Star Ferry. Head for Lan Kwai Fong for great night life.
May 10: Go to the Peak and spend half almost half a day there. After going down, you can roam around the Central for some shopping and walk to HK-Macau Ferry Terminal near Sheung Wan. There you can take a ferry to Macao. After dropping-off, walk to Fisherman Wharf for fun.
May 11: The Wine Museum and Grand Pix Museum are recommended for a visit. Afterwards, take a taxi to the Ruins of St. Pauls and Senado Square for fun. At night, go to Grand Lisboa for experience the gambling.
May 12: the Macao Tower, A-ma Temple and Venetian are recommended.

Hope help!
