The transverse spectra and interferometry volume of thermal pions in A+A collisions were estimated basing on the chemically frozen hydrodynamic evolution that incorporates the decays of resonances at the freeze-out stage. We found that the resonance decays could increase significantly the pion interferometry volume, while the pion spectra slopes are not affected much by the decays in the region up to transverse momentum 1 GeV. We also notice that in such a model the resonance contributions reduce the ratio of outward to sideward interferometry radii.
