We compute the action, entropy and conserved mass of these spacetimes, and find that in certain instances the mass and entropy can exceed that of pure de Sitter spacetime, in violation of recent suggestive conjectures to the contrary.latex, 6 pages, 2 figures, discussion on entropy expanded, version to appear in Phys.
