I'd rather be cremated... More space for this over-crowded world. My mom's the same way. We both do not want to become ugly and filled with worms, anyway.
(On TV, I heard that some places in Japan (or was it China?), that it's so crowded that they have to put the grave-sites on top of buildings! Ewwww! Imagine something dead living above your roof! This is many years ago, though.)
