Northumberland - is 2 weeks too long?

[verylapsedrunner]

Finally we're going to make it to Northumberland this summer (been on my hit list for some time). Would a week near Bamburgh/Lindisfarne to do the beaches/castles followed by a week right beside Hadrain's Wall be overkill? We would be self catering, enjoy the outdoors and will have the dog in tow. DS(6) heavily into castles & Romans. I don't really want to base ourselves somewhere between the 2 as would rather have the full on castle/beach/Hadrians Wall experience without having to do full day trips.
Am I mad?

one week in and around bamburgh (1 day in castle, 1 day doing seahouses and farne islands, 1 day on lindisfarne, 1 day in anwick gardens/castle, 1 day in ford and etal) When I first read your OP thought eekk what would you do but yeah I reckon from my brainstorming above enough to do for a week near bamburgh and loads to do near hadrians wall. Hope you have fun.

I found 1 week too long when I was there last summer, though it did rain all week.

We went to Lindasfarne one day.
a boat trip one morning and a castle in the afternoon.
went to Cragside twice.
Anwick.
day trip to Newcastle.
Hadrian's wall on the way up there.

Not sure how I managed to create the same thread twice. Thanks for the feedback, keep it coming please.
