Acropolite, if you have never been there before, be prepared for a shock to the system. I have lived in the tropics on and off for 12 years, and this last time was unbelievable. The locals are even complaining. It is TRULY oppressive. This is what is called the buildup, and you really have to experience one to have any idea how hot and humid it is. Most people spend a lot of time looking at the sky praying that the clouds turn into thunderstorms that will drop their load on the place and cool things down. Without airconditioning and I mean refrigerated, it would be absolutely unbearable. I stayed at a mates place about 30km down the track and luckily he has all bedrooms air conditioned, as an example, I took my video camera out of the bedroom to do some filming, and it took nearly 20 mins before the lense cleared. It just went opaque from the change of humidity.
In my experience mould does not become a problem as such until the continuous rains start. Enjoy, your stay because it can be a great place to stay. Oh yeah when the thunderstorms start they are a sight to behold, I think probably the most spectacular storms on the planet, and this view is held by a lot of people.
