Using (even possessing) a false ID is a crime, which happens to be a Class B Misdemeanor. Furthermore, it may open the ability for the minor to be charged with other offenses, such as check fraud. A minor generally cannot stay at a hotel on his own as hotels have a policy of only allowing their rooms for adults. The kinor can go to uvenile detention if caught but likely that record would be sealed when he attains the age of majority (turns 18).
Here is the law:
S 190.23 False personation.
