There are few options to import an external catalogue, all require some familiarity with programming techniques:

1) use TouristWay Administration API to import their catalogue from a database or file or XML feed (we are preparing documentation about this)

2) use TouristWay Widget to embed the output of the external booking engine in an appropriate area of your site. This option will not allow to reserve those items and mix them with products loaded through TouristWay administration area, but you will still be able to collect email requests.

3) buy Operator edition: unfortunately this will dramatically raise your project's costs but we'll do all the job for you. An average project based on Operator Edition integrated with an external GDS or reservation system starts from 30.000 $.

Sound trivial, but you should also consider to manually enter the services you actually mean to sell and which are relevant to your product/offer, sometime is just easier if you account the efforts required to build an actual integration.
