Many seniors miss out on hotel discounts due to not asking about them when booking. It's also common to forget to present valid ID or senior cards at check-in, which can lead to missed savings. Some may not research or compare offers from different hotels, leaving money on the table. Additionally, seniors might overlook the specific terms and conditions attached to these discounts, like booking directly through the hotel. Always check with the hotel beforehand to ensure you have all necessary information and documents ready.
