Skegness, been there loads of times probably more than 50 mainly when I was a kid, if you like chips and fish, kiss me quick hats, rock, amusement arcades it's great if you look on ordinance survey you'll find a few walks, nice to go to Boston you can climb the Stump, Lincoln is not far but as I get older I only go for the day every 5 years as I now hate it!
Lee I recommend don't go for more than a day trip because if it rains you've had it, I would spend more and go sight seeing in London.
