Travelodge ( uk stay )Watch
I have made loads of travelodge bookings and ive not been asked for my id. i just take a print out of the booking, so show the booking email on my phone and said my name. Take your id just incase, but you wont need one for the 17 year old.
It’s very common. Every night there will be a couple of rooms at least in every hotel that are used for an hour or so because two people just need a bed rather than a place of sleep.
