most likely they came from "Gold" 27 de Febrero inside the Ramada Hotel (second Flor). One of the best clubs in town.

Because it is "Part of a Hotel" no Businness Closing Hour Regulations apply. People usually go there after all the other clubs are closing. Amazing Place, you are going to love it !!! Just don't show before 1 am. btw. next time go to Adrian Tropical at the Malecon. Also open 24/7 on the weekend. People leave the clubs at 5-7 am and go there. (at least that was the practice before covid)
