Can my friends and i go here for 1 night after we graduate from 8th grade in 2019

You have to be 18+ to check in at ANY motel.

Yes need someone 18 or older to rent the room

18 years and older only

You could call and ask...but you'll probably have to have an adult present, since you have to rent a room with a credit card. I'd have an adult present for safety...
