I’m not entirely sure on the leadtime, because I wasn’t the one who actually booked it. It sounds like you definitely want to book it sometime between December to April. The summer is pretty dang hot and humid and is during the rainy season. Otherwise, it is my understanding that it never rains during those months I mentioned. We hardly ever saw a cloud in the sky.

They book it in one week blocks because everything is on a certain schedule and routine.
