As far as I know, heaven isn't very well defined. It is basically whatever you want it to be, just like how you can cherry-pick which parts of the bible are true. Do they never realize that their desires do not change reality? (Or do they assume heaven will conform to their desires). In all honesty, especially given god's character, it would probably be endlessly worshipping him and being bathed in his 'glory'.
