Kids pushing baby strollers, who should probably still be riding in them! Just went to SF Marine World in Vallejo, CA (*Sigh*) and I nearly got tripped by one of these stroller-pushing adolesence...
Also, they only had one train running on all the rides. MAJOR annoance. C'mon hour and a half wait for Kong!? Not worth it. In fact, they don't have anything there that I'd be willing to wait two hours for... (Medusa being the only *possible* exception, but that still didn't look too impressive. Guess I've been spoiled by CP & PKI.)
