Some hotels require a credit card as a guarantee and if you are currently working and have excellent credit rating then the bank will issue you a credit right away. But I would guess at least when you are 18 years old.
No age as long as you have the money to pay for it
I think it is 18 but it depends on the hotel. Some want a credit card while others settle for cash. Just depends on where u want to stay.
