Arrive in Macau by Ferry at 09.00 morning 09 June and stay one night at Hotel Sintra

First of all, I’d make some changes of your itinerary:
Day 1: Macao Port – Na Tcha Temple – Ruins of St. Pauls – Monte Fort - Largo do Senado Square –Harbour Cruise (60-90 minutes)
Day 2: A-ma Temple – Macao Tower – Venetian

1. From the port, you can take the free shuttle bus to your hotel for check-in first. The attractions listed on 1st are all within walking distance to your hotel. After visiting Senado Square, head for Ponte 16 to take the Harbour Cruise.
2. From your hotel to A-ma Temple, you can take bus no. 18. Bus no. MT4 or 5 can take you from the temple to Macao Tower. To Venetian, bus nos. MT4 or 26A would help.
3. Take the free shuttle bus of your hotel to the Maritime Ferry Terminal directly. There you can easily take a ferry to Hong Kong.
