Will my website show hotels in small towns as well as the big cities?

Yes, in most cases you will get hotels in smaller towns as well as the big cities, but the choice will not be as deep and you should check your own key destinations before you promise anything to a customer.

The hotels on a booking website come from the suppliers you are connected to, and every supplier has its own strengths. Some are strong across one region and thin everywhere else, and nearly all of them carry far more properties in cities and resort areas than in small inland towns. A search for a well known city will usually bring back a long list of properties, while a search for a small town may bring back only a few guest houses and roadside hotels, or sometimes nothing at all.

When a particular region really matters to your business, the usual answer is to connect more than one hotel supplier, because where one is weak another is often strong, and the results can be shown together so your customer sees one clean list. Whether that is open to you depends on your plan and on the contracts you are able to sign with the suppliers themselves, so it is worth raising early rather than after you have gone live.

The sensible thing to do next is to write down the places your customers actually ask for most often, search each of them on a test portal, and see what comes back before you settle on which suppliers to take.
