I forgot to cancel the hotel booked by Ctrip and didn't check in.

If you booked a hotel on Ctrip, but didn't check in and forgot to cancel the order, you can try to cancel the order in the following ways:

1. Call the hotel front desk directly, explain the situation and provide the corresponding order information, and request to cancel the order.

2. Log in to Ctrip app, select "Hotel Check-in" on the main page of the software, find the order in "My Order", and try to click Cancel.

Either way, it is recommended to cancel the order in time to avoid unnecessary trouble. If you encounter any problems, you can consult Ctrip customer service for help.
