everyone does have their opinion. personally I'd keep L/P, E/S, C/T, J/D everyone else adios. get rid of the big girls house get 2-3 smaller apts, with 2 maybe 3 girls per.
for the girls vaca apts, do not bring in married/engaged girls. and for gossake no live in guys we have seen that. if they want a couple of guys on vaca apts for the women to ogle be my guest. maybe even get a couple apts in Russia where they can rotate women through. every month or so let the viewers decide if someone stays.
