Out of curiosity, can you use your college ID as a form of identification when you're checking into a hotel? Or are there certain specifications for IDs that can be used for that?
Depends on the hotel. Many require an official government-issued form of identification. So while a lax/kind hotel clerk may let you off with just the student ID, it's highly likely that they could reject it, and you'd probably have no legal recourse, lose your money (if in their terms) and be without a bed for the night :/
For an example, here's a random one from a quick google:
According to government regulations, a valid Photo ID has to be carried by every person above the age of 18 staying at the hotel. The identification proofs accepted are Drivers License, Voters Card, Passport, Ration Card. Without valid ID the guest will not be allowed to check in. Note- PAN Cards will not be accepted as a valid ID card.
Again, it'll depend on the hotel, and sometimes the laws of the country.
