we were at LHP at Serenity Bay on Thursday, July 4th, and the flies were a problem for me. it seemed like a couple dozen were near the fish. when we went to a table, there weren't any until one of the servers brought over fresh grilled rib eye and then there were at least a dozen of them and I was swatting them away. the spinning fan worked for the immediate area it covered, but the flies were around the table. once we finished the ribeye, almost all the flies left us. did not check any of the other food service areas.
that being said, the beach and the water is amazing. we walked down to the lighthouse, about a 25-30 minute walk from Serenity Bay. beautiful scenery.
the walk from the ship seems daunting but it was fine. we did get lucky in our return to the ship because it was cloudy and the sun wasn't as harsh. overall, it is a great addition, but the only wrinkle are the flies.
