We study to what extent a measurement of the m_\ensuremath⊥ spectra for hadrons and their resonances can resolve ambiguities in the statistical model description of particle production. We describe in a quantitative analysis how physical assumptions about the freeze-out geometry and dynamics influence the particle spectra. Considering ratios of m_\ensuremath⊥ distribution of resonance-particle ratios (such as K*/K, \ensuremathΣ*/\ensuremathΛ,\ensuremathη^\ensuremath'/\ensuremathη) we observe significant sensitivity to fireball freeze-out geometry and flow dynamics.
