Adventure operator Explore has frozen the price of land-only trips until August amid pricing uncertainly following the Brexit vote.
The price freeze covers bookings made by August 1 and comes on top of a guarantee that no extra surcharges will be applied once trips have been booked.
Product and operations manager John Telfer said: “Right now, there is a high level of uncertainty in the currency markets.
“Customers who have already booked with Explore can relax in the knowledge that they won’t be charged a penny more.
“But for those thinking of booking, we’ve decided to freeze holiday prices for the land only part of the trip.
“Flight costs by their very nature vary on a day-to-day basis, which is out of our control, but once a customer books and pays their deposit, the cost of the whole trip will not change.”
