@Valarie17 Third party bookings are only allowed if you are registered with Airbnb to Work and booking a business trip.
You should also be looking on the regular Airbnb site where you plug in the variables, city, number of guests, etc. and see what comes up. I don't know how much luck you will have finding multiple homes near each other, but you can try.
You should be prepared for a number of hosts to not want to host 'a football team' for fear of damages and parties.
