Kansas City Chiefs fans seem way more amped up for Super Bowl LVIII than their San Francisco 49ers counterparts ... at least in terms of interest in short-term rentals in Las Vegas.
The good folks over at Airbnb tell TMZ ... searches for rental listings in the Las Vegas region are up by more than 65% for the week of the Super Bowl, and most of the potential renters are flocking in from KC.

Airbnb says Chiefs fans were in a frenzy looking up places to stay in Vegas after Patrick Mahomes and Travis Kelce beat the Baltimore Ravens to secure a spot on SB LVIII .
