Activities such as outdoor adventure, sightseeing tours and tickets for attractions will be bookable through Travel Trolley’s new holiday extra section.
The offering is a new addition to the online travel firm’s website, traveltrolley.co.uk.
Tickets to 200 amusement parks including Walt Disney World, Universal Studio and Disneyland and more than 5,000 sightseeing tours are available.
The holiday extra tab also includes car hire and transfer options.
Holidaymakers browse by destination and dates of arrival and departure and are given e-tickets.
Sales director Jaymin Borkhatria said: “Our new holiday extras section will provide our customers with a fantastic choice of things to do at any destination.
“By providing this do-it-yourself option to book tickets for excursions, tours, amusement parks, theme parks and other activities, we have also given holidaymakers greater control over their holidays”.
