Immediately after booking, we got a text confirming our tour. We were picked up on time and it was a quick 30-40 mins to Sosua beach. They chartered everyone about 10 to 12 people at a time on a smaller boat out to the Catamaran waiting in the harbor. It is a slow process, but it wasn't terrible at all.
Once we got onto the Catamaran, we snagged an area over the netting. We were warned that we would probably get burned (and we did) but it was worth it! Once the boat gets going, being over the netting was amazing.
We stopped at 2 snorkeling sites. Both were awesome. They even let us jump off of the side of the Catamaran.
Then we sailed along the coast line while we ate, drank, and danced. The food was great, best food we had in the DR. The drinks were plentiful and Alex and several other employees were quick to grab you anything you needed.
My wife, my 3 teens, and I all thoroughly enjoyed the day. I highly recommend!
