Is there a disco for late night entertainment on site? Or is the only option to travel to their sister resort 20 minutes away? The resort's description says evening program or lobby music so it seems rather vague.
There is not a disco. There is a theater type setting where they have entertainment at night
Everybody is right however, there is a club on the same street as the hotel. It's about 3 miles down the road on the left hand side. The name is , the jungle. It's for locals and vacationers alike.
Every night they have a different theme. Like one night was a Michael Jackson impersonator, and another night was Bob Marley music. People dance wherever, but mostly it's like a sit-down type of venue, never really saw a "disco". The sister resort is down the road, I only saw it during the drop off and pick up of the guests who stayed there (on way to/from airport) and since it was stop and go I couldn't tell you if it was 20 minutes away for sure. For nightlife action, I recommend finding a local through TripAdvisor with high reviews. Hope this helps you, feel free to ask further questions! :)
