Business trip - 2 times/multiple

Hello, our group will travel on 14th of October from Budapest to Hongkong (15 people). The hotel will be in Shenzen. The program is: 1st day Shenzen, 2nd day Hongkong, 3rd day Macao, 4th day Shenzen, 5th day Honkong and travel back with plane. Thatswhy I asked for a multiple business M for them but we got 2 times entry business M, valid for 30 days/entry. Is is a problem for us? Because the hotel will be in Shenzen so I calculated we need multiple visa.
