You have not given the detailed facts with respect to the charge that you are facing for contributing alcohol to minors. However, if you purchased the alcohol and did not safeguard it against the use by minors and the hotel room was in your name where minors drank the alcohol, then there is a chance that you could get convicted of the charge that you are writing about based upon a decision by the trier of fact if you go to trial.I suggest that you consult with a criminal defense attorney to defend you regarding this matter.
