The Lake District's a good bet. Scenery, good roads etc. Not sure about campsites. Then there's always the west coast, Oban, Fort William etc, etc. Plenty good roads out that way and definitely plenty of scenery! Obviously you just have to take pot luck with the weather although in all the years I've been visiting out Oban way I've had more good weather than bad. Plenty of campsites out that way. Ballater's a nice wee place too and quite near Balmoral, Royal Deeside. Aberdeen's not too far from there too if you need to do a city thing whilst there. Again though, not sure about campsites.
New Zealand should be nice mind you!
