I would to take relax holiday at Macau for 4 day 3 night from 6/6-9/6 Any suggestion?

Although you want to have a relax holiday, I still think four days are a little bit long.
I think two days can cover most of the attactions in the city such as Ruins of St Paul, Senado Square, the Grand Lisboa, City of Dream, the Fisherman Wharf, the Macau Tower, Ama Temple, Avenida de Almeida Ribeiro, the Monte Forte and the local museum.
I think the local free hotel shuttle buses are the best transport when you were there.
