We were just there Saturday. Did not notice any flies around the food or tables at True True. There were a few bees or similar around the soda machines.
We did see a few - like maybe 2 or 3 - flies at one station in the Serenity Bay food area - not on the food. Just flying around. Didn't see any around the tables, but we didn't eat there.
Saw the most flies during the nature walk - and that's ok since I guess they are technically part of nature. lol
