Thanks for the support for British food, Pam! And you are right, we have some of the best chefs in the world, as well as some of the best food stores! (Mind you, I've never seen any of the US chefs except for the little Frenchman, whose name I forget, so cannot comment on all the chefs mentioned on this site!)
Thier. I hope your holiday plans come to frution. As to what is 'do-able', that would depend very much on what you wish to see. For instance, Edinburgh is worth at least 3 or 4 days, just on its own - we have the Castle, Holyrood Palace, the New Town (from late 1700s!), the Auld Toon, Greyfriar's, Grassmarket, Canongate, Royal Mile (C'Gate is part of the Mile long cobbled street between the Castle up on the rock, down to Holyrood Palace).... If you want to visit the Highlands then a car would be the best way to get aound, but I warn you, some of our roads are considered quite 'hairy' by tourists - single track with passing places only..... and you'll be driving on the 'wrong' side of the road! Isle of Skye is pretty and worth a visit, Perth, Inverness, Scone - and that's not even mentioning the Borders area, or Glasgow (yes, lots to see and do in Glasgow!)
Goodness..... I sound like a travel documentary! If you need specific advice, PM me nearer the time and I'll see if I can be of any help to you!
