FYI, i got onto the UK, online help and this is the response I got.
You are now chatting with 'Laura'
Laura: Good afternoon, How can I help?
you: hi there, i was wondering how come it is much more expensive to book via keycamp.co.uk as opposed to keycamp.ie for the very same thing? as in club farret in languedoc
Laura: Hi there
Laura: If you can bear with me one moment, i'll check this with the pricing team for you...
Laura: Won't be too long...thank you
you: may for 14 nights is £736 on uk, but only €528 on ie site, a difference of approx €350
Laura: Thanks for your patience...I've just had a quick work with the manager who has explained the reason for this difference. It appears that certain resorts will appeal more to either the English or France market at different times of year. Club Faret will be under higher demand from the english market and this will therefore reflect in the prices
Laura: You may find there are other resorts that work out cheaper on through the English website (keycamp.co.uk) it will totally depend on the demand based on previous years...this is something that our pricing team investigate and set up based on historical bookings
Laura: I can see from "Visitor Info" that you actually reside in Ireland? In this instance, your parc choice/time of travel is obviously working out better for you booking through Keycamp i.e under the euro rate...
you: yea, i had clicked a link from another website which brought me to the uk version. i just thought it was weird and was making sure it was the same thing i was getting
Laura: Absolutley, You will still be booking the exact same site/accommodation...don't you worry :-)
you: will tell all my uk mates to book via .ie from now on
Laura: :-) It's definately worth comparing the 2 yes...as I say, It can depend on parc choice, dates etc though but worth checking, why not!
you: thanks a bunch
Laura: You're very welcome! Is there anything else I can help with today?
you: no thanks, all sorted now, have a good weekend
Laura: You too, All the best
