From what I could put together, Happy Bay is the base for daytime entertainment and the evening entertainment is held at various inland places around the island. It is difficult to understand the website.

If one goes to the facebook page there is a Transportation & Venue Map that lists some of the locations, with Happy Bay being listed as the "Main Venue". I have no idea of the accuracy of the map. It is listed as being for 2019 but may actually be a map from last year.
