hey all, im heading off to ptuj in slovenia for the european juggling convention

It should be an amazing week and from what I've heard, Ptuj is an ideal location for it. My main query is getting from Budapest airport to Ptuj itself. As I am flying from Manston I have no option but to fly to Budapest instead of Ljubiana which would have been much more convenient. Ideally a bus would be fine as I'll be getting there a day early so time isn't a factor. I've searched the net for bus companies that do a transfer but with no luck. Any help in this matter would be greatly appreciated.
