Few question:

1. How to get to Sabana de la Mar from Santo DOmingo. I've heard that there r buses going every hour from somewhere near avenida Duarte. I wanted to confirm that, and what is the earliest time i could take the bus on sunday

2. Me and my friends would like to go In Sabana de la Mar and find someone to rent a boat to see whales. We dont wont to go with a tour cause its tooo expensive. So anyone rented a boat there? Any ideas how much could it cost? How many ppl should go?

Let me know PLEEEASE
