Yes. with photo id .... and as a precaution. take your passport, you will not get out of the airport without that special little book.
Aside from the airport, your passport is unnecessary. A valid picture on a driver s license is sufficient. Don t carry other documents with you as pickpockets and robbers could make your stay in Las Vegas much longer than you expected.
A driver s license is accepted IF there is a valid picture and the license has not expired. However, sounds like you may be close to 21 so better idea to carry passport in case there are other problems.
