When I last went through this situation wearing proper shorts was deemed to have made a more positive difference than any of the saddles we tried - i.e they all went from "uncomfortable" to "ok"... none were initially considered ok on their own.
I appreciate this may not exactly fit with the "no long rides/priest bars" scenario though! However it might buy some time to, at least, get used to a particular saddle - which may be all that's required for short rides?
