Tall ships in Charlestown Harbour in Cornwall, England- I love this little harbour if you're ever in Cornwall it's well worth a visit, full of history, It has been used as film location several times including for - Mansfield Park - Moll Flanders - Tim Burton's Alice in Wonderland and an episode of Dr Who
your game of thrones travel guide (infographic) ..it would be cool if down the road, after the series wraps, they would create a got-location tour. something akin to what they do for lotr in new zealand. it could get creative quickly. possibly asoiaf themed food/music/decor on the ship...guides dressed as people from that world etc. i would totally get my geek on.
