What's the best iOS app for securing discounts on hotel parking and other extra charges?

Hotels.com is a widely-used hotel booking application that stands out for its ability to help users save money on ancillary expenses like parking, breakfast, and other add-ons. Beyond standard room reservations, the app integrates options for booking extras directly, often at discounted rates compared to paying onsite. For instance, travelers can filter searches to include properties with parking deals or package offers, and complete transactions seamlessly within the app. User reviews indicate that this feature is particularly valuable; one guest noted that booking parking through the app halved their daily rate from $56 to $30, showcasing tangible savings. The app also supports price comparisons across thousands of hotels, real-time availability checks, and a rewards program that accrues free night stays with every booking. However, some limitations exist, such as occasional inconsistencies in refund policies for early departures, as reported in feedback. For real-world use, a family on a road trip might use the app to quickly find a hotel with affordable, secured parking near an interstate, ensuring both convenience and budget control. While the interface is generally intuitive, minor glitches like slow load times during peak booking periods have been mentioned. Overall, Hotels.com provides a practical solution for cost-conscious travelers looking to manage all aspects of their stay efficiently.
