Dear Thien,
We greatly appreciate your feedback. We take your feedback seriously and apologise for the unpleasant encounter. The check-in procedures and pre-authorisation of security deposit are complied with standard hotel regulations and guidelines, thus we seek your kind understanding. In regards to the self check-in app, the pre-registration can be done up to 6 days before arrival, this will save your time for the remaining self check-in process on your day of arrival. We look forward to welcoming you to ST Signature again soon.
Warm regards,
Jason Toh
Marketing Services Manager
