It SHOULD be hard for a large group to be stealthy. If you want to sneak up on someone use a small group, or get your skill bonus ridiculously high via Expertise/Pass Without Trace/Invisibility. Three dozen bugbears simply SHOULDN'T be able to all sneak up on the same party without someone giving themselves away, and that is perfectly fine because quantity makes a dandy substitute for surprise.
Group Stealth checks are inappropriate and unphysical.
