I've booked myself at the Ink Hotel in Amsterdam in a few weeks. After Amsterdam, I'm planning on meeting with a friend in London, though she'll be in London while I'm in Amsterdam. If I book an Accor hotel (specifically the Ibis Shoreditch) under my name and my acount, but she checks in before I get to London, will that throw anything off? Or would it be best if she books a separate reservation for the days she'll be there on her own?
