We revisit the use of ideal hydrodynamics to describe bulk- andmultistrange-hadron observables in nuclear collisions at the Relativistic HeavyIon Collider. Toward this end we augment the 2+1-dimensional code "AZHYDRO" byemploying (a) an equation of state based on recent lattice-QCD computationsmatched to a hadron-resonance gas with chemical decoupling at $T_{\rmch}\simeq$160\,MeV, (b) a compact initial density profile, (c) an initial-flowfield including azimuthal anisotropies, and (d) a sequential kinetic decouplingof bulk ($\pi$, $K$, $p$) and multistrange ($\phi$, $\Xi$, $\Omega$) hadrons at$T\simeq110$\,MeV and 160\,MeV, respectively. We find that this scheme allowsfor a consistent description of the observed chemistry, transverse-momentumspectra and elliptic flow of light and strange hadrons.
