It Depends
on what you are looking for in a resort. On the beach? Good value off the beach?
My wife and I go to Fun Royale-Fun Tropicale in Playa Dorada. Have been going for 14 years. The resort is probably a 3-3.5 star resort at best. However, the staff is awesome. The food is good with quite a bit of variety. The food at the beach is great.
The beach is nice 8-10 minute walk from the resort, but you can ride the shuttle if you don't want to walk. 3-3.5 is good enough for us because we don't spend our vacation in our room.
Playa Dorada is just a few miles outside of Puerto Plata and the city is a fun place to visit. From what I hear about PC, it's only resorts. It's POP for us.
Enjoy your Dominican experience!
