Thanks again everyone for all the good info.
Just wanted to tell you that Wanna Dive Hut has confirmed that they do NOT have running hot water in the rooms. ---"The rooms don't have running hot water, but the water is not cold. For a hot shower you can use the public hot shower as well."----
I'm am not saying that hot water is necessary or that the Wanna Dive Huts are not a wonderful place to say. I am simply passing on the information to anyone who might be searching for it as I was. I hear nothing but goods things about their operation.
All that being said...It would seem like that is something that should be mentioned on their website. From a traveler's standpoint, I normally wouldn't even think to ask that question while booking accommodations in a confirmed, popular resort/holiday area.
I'm glad I found out beforehand on Scubaboard.
