Canoa Coral by Hilton is in Bayahibe. Bayahibe is about 15 - 20 km. from La Romana (eyeballing it from my map).

Gregg is right about the Canoa Coral. It is on the Dominicus Beach in Bayahibe, about a 10 minute drive from the townsite of Bayahibe (30 minute drive from La Romana) and a rather long walk along a hot and dry highway if you choose to do that. You can't really get there along the beach in the normal fashion. Mid-way up the Dominicus Beach is a private home so you may not be able to access the beach there and then once you pass the Iberostar, it turns rocky and unmaintained so good hiking footwear would be helpful.

Part of your confusion about Juan Dolio may be in that there is the Hilton Coral Costa Caribe in that stretch. Many people become confused in that they want the amenities of the Canoa Coral but like the situation of Juan Dolio and proximity to Santo Domingo. As long as it is the Canoa Coral that you are after and you're happy with it being in Bayahibe, then you're good!
