In a tropical environment, especially if wildlife could get in there, yes, there would be only bones in a few months.
Vultures can clean up all but the toughest sinews in a day or two once they pick up the smell and in that climate there would be a smell a vulture could detect within hours. Ants and other creatures would pick the tiniest bits off the bones very quickly after that. I don’t think there would be much other than bone and some hair left after a week. That is based on what I have seen happen to dead animals in South Carolina in summer back when the buzzard population was much, much higher than it is now. Since humans have very little hair they would not last as long before becoming bare bones as other mammals. I have seen a dead cow with buzzards pecking away on the outside and several possums eating from the inside at the same time.
