Visa for Zhuhai and Macau

Good day, We are German but living (with PRA VISA) in the Philippines. Will travel in March to Hongkong. Want to go direct to ZHUHAI (booked already Hotel for 3 nights). Then we will go back to Hongkong where we want to stay for 1 night more until on day 5 in the morning we will flight back to Cebu.
As I understand is there no need for an advanced entry permit. Will get there one entry permit for 72 hours (right?).
But... may we go to visit Macau?Taipa (Venetian Hotel) for a Day Tour or do we need a special entry permit for this? Can we get it there at the Port? How much would it be?
