There have been numerous threads over the last few weeks asking TA to expand the list for amenities and services offered. I think many of us agree that it certainly couldn't hurt to define as clearly as possible things like pets allowed, smoking allowed, handicapped accessible, credit cards accepted, etc. The perceived problem is that accuracy and maintenance of this information could be, shall we say, inconsistent.
Here's my solution. Wherever the amenities/services are listed (yes, it's different for hotels than restaurants), post a comprehensive list with a simple, "Yes," "No," or "Call" next to each amenity. If it is confirmed one way or the other, post "yes" or "no." If it is uncertain, post "call" (or "inquire within," or however they want to say it). My reasoning is that, while having the information posted to a listing is convenient, accuracy could be a problem. Therefore, prompting the reader to call ahead for information that isn't readily available to TA could solve a couple of issues right away. At the risk of adding a little clutter to the amenities list, I'm thinking this could help in some way, especially for amenities that are less commonly requested. Just a thought
