Planning a vacation

hello everyone , another anglophile here from texas. i'm planning a trip to england, not sure when yet, but sooner than later . would it be silly to want to start my trip in cornwall ,in port isaac, specificly to see the town where "doc martin" is filmed , then making my way to london(and the various marvels) , finally making my way all the way up north? does that seem like a realistic path?

I personally don't see why not - but possibly easier to start in London as you will most likely be landing there, then make your way to Cornwall and North from there, then across to the west and down again to London to catch your flight home!
