We are a group of 7 adults flying in for our cruise in June. We are staying the night before in downtown. I came across Express Shuttle Miami. Anyone used them before? Good? Bad? Looking for recommendations without breaking the bank. We could do uber xl but then we would need 2 every time and I'm trying trying to prevent the group having to split up. We would need shuttle service from MIA to Downtown, Downtown to the Port, Port to MIA.
