Using a website aggregator to book hotels, cars, etc. is a real time saver. You can see maps of areas and available facilities and prices.
BUT, one of the biggest has apparently decided that they no longer need people to service customer needs. If there is an issue with bookings, website access, etc. you are at the mercy of their AI agent
We had an issue with a firm's website; displaying our multiple hotel reservations. The phone tree had NO option to talk to a person. The Chat was clearly AI, and when it was unable to resolve an issue, referred to the phone number that had just sent us to the Chat window. Exhaustive search on the Internet revealed no 'secret' phone numbers. Email address did not respond.
All I can do is to suggest you try CALLING any site that you use for bookings (there is a hint of who they were) an verify that you can talk to a person if there is an issue.
We got through the incident because I had noted a reservation number and was able to resolve the issue with the hotel directly.
Be prepared....
