No, you do not need to contact the airline or hotel yourself for anything you booked through us, because we send the cancellation to each supplier on your behalf. Just tell us clearly which booking you want to cancel and whether you mean the whole trip or only part of it, and we will pass the request on and come back to you once each part is confirmed cancelled.
The one thing to watch is anything you arranged separately and directly, such as a room you added yourself after the trip was booked, a seat or bag bought on the airline website, or a tour you paid for locally. Those sit outside your booking with us, so you would need to cancel them with whoever took the payment. If you are not sure which parts came through us, ask and we will tell you exactly what is covered.
Please treat a cancellation as final only when you have it in writing from us. Telling us is the request, not the result, and a few suppliers take time to respond, especially outside their office hours. Until that written confirmation arrives, assume the booking is still live.
What the cancellation costs you depends entirely on the fare rules, the hotel policy and the supplier, not on us, and those vary a lot from one booking to the next. As a general rule, cancelling earlier gives you a better outcome than cancelling close to departure, so it is worth telling us as soon as you know your plans have changed, even if you have not decided for certain yet.
