In the Philippines, hotels are required to offer senior citizens a 20% discount on room rates, as per the Expanded Senior Citizens Act (RA 9994). To avail of this discount, seniors must present a valid Senior Citizen ID upon check-in. It's important to note that this discount may not apply during peak seasons or on promotional rates, so checking the specific hotel's policy beforehand is advised. For the most accurate information, seniors should inquire directly with the hotel or refer to local regulations.
