Bahia Principe Aquamarine was our first trip to the DR. We didn't know what to expect, but based on previous reviews, we thought it sounded good for an all-adult/inclusive place, and it did not disappoint. It's clean, safe, fun, and entertaining. Access to the pool and beach were easily accessible, given that they have golf cart-style shuttles throughout the resort. The food was amazing, but if you want to experience DR to it's fullest, I suggest booking DR tours which was provided to us by a booking agent (which I believe works through expedia) once we got there. We did no prior booking before our arrival. I highly recommend this place for first timers, especially since it's adults only.
