I would take the net, expecting it might not be required. Here in Uruguay, I sleep with a net around my bed, and I accept it as part of life even when we are out of mosquito season. I like it, so I have a favorable bias. But I do not like bites. Even without the risk of what they carry, bites make me itch terribly, and I do what I can to avoid the potential of them. Nets, spray, patches. I even drink water with a splash of vinegar. If mosquitoes are a concern, treat them accordingly.
My advice, take the net. You will kick yourself if you need it and don't have it.
