Hidden hotel charges can appear on a credit card statement weeks after your stay, even if you paid your balance at checkout. Generally, these phantom charges include amenities like Internet access and parking. Be sure to scan your credit card statement to be sure you were charged the correct amount — and not charged twice.
Also, be wary If you’ve used a voucher for a meal at the hotel restaurant; the discount may suddenly disappear. The worst offense I’ve personally experienced was when the shopping spree of another guest was charged to my room.
If this happens to you, just contact the billing department at the hotel. They understand that this happens and are happy to work with you.
