I've used booking.com several times and am comfortable with the site. I currently face a new situation with a booking, on which I'd like advice.
I've made a booking through booking.com for a 1 night stay in a hotel (big chain) in Frankfurt Germany, for my girlfriend, using my credit card. This is a non refundable booking and the option of `no prepayment, pay at the hotel' was absent. I'm fine with that, as it is a good rate and I won't change or cancel the booking. My girlfriend does not have a credit card, so I'm paying for her. The booking is in her name and I won't be at the hotel with her, as we start our holiday from different countries (she needs to spend a night in Frankfurt before an early morning flight). If she does have a problem at check out, I won't be contactable, as I'd have boarded my flight from another country.
I wrote to the hotel, which confirmed that my card will be charged directly (email copied to my g/f). I'd like to make quite sure she is not asked to pay (except for incidentals) or produce a credit card. I'm ok giving her a copy of my card and PIN, if required. Am I missing something? Is there anything else I need to do.
