You would take a RD$120 bus from Bavaro bus stop to Santo Domingo. This bus leaves Bavaro at 7 am and 4 pm. It is a four hour trip so you would have to overnight in order to make the 11 am Caribe Tours (Tel. 221-4422) five-hour bus trip to Port au Prince. But you could make the Terra Bus trip departing at noon and costing US$75 round trip, or US$40 one way. Tel. 472-1080. Take a RD$60 taxi to the Terra Bus station at Plaza Criolla, about 10 minutes away from where the Bavaro bus will drop you off.
