Just back from Roseau stop. Yes, you can get a taxi to Mero Beach, $30 each way, ~30 min drive. I would give it a pass. Stay on the ship if you just want to enjoy the sun. Chairs are hard plastic. Umbrellas are OK if you look around at the different beach bars. ($20 for 2 chairs and umbrella) Beach is in a small town, on the main road and not peaceful. I love beaches, but would not go back to Mero. There are tours to the waterfalls and sulfur springs, but also long drives on not the best roads.
