Hi
I’m sorry but that is not possible using this plugin. It takes the feed from Tripadvidor using the old style feed which is no longer supported by TA.
You could try using the basic rss feed for the business in a normal rss plugin using the xml feed
You need to use the xml feed of: http://www.tripadvisor.co.uk/Feeds-d1535306-treviews.xml where the d1535306 is the business code for the business feed you want to display.
you will only get the review title and excerpt. You will not get the rating image etc but you should be able to set the number of reviews to any number between 1 and 10 depending on whether the rss plugin lets you set the number. I think the default rss widget that comes with wordpress allows you to do that.
