<prompt> Human: Hi everyone, first post here. Im not sure if theres a better place to ask this question - if there is, please direct me to it.This is my first time travelling abroad by myself. I reserved and paid for a hotel room in Germany a month and a half ago. When I checked in today, they asked for my credit card so far, so good. As soon as I got into the room, I was greeted with an email saying that they had charged 1,000 to the card. This is more than I paid in September; all the more, I thought I had already paid for the room.What Id like to know is whether or not this is par for the course for hotel charges - is this 1000 charge a placeholder of some kind, or has the hotel attempted to double-bill me?  <response>: Sometime hotels will put a hold on money in your card, in case of incidentals say you use stuff from the minifridge, etc.. But in my experience its usually like 50100. If youre still at the hotel, go back and ask them whats up.
