Hi, I have loved here for 16 years now!
Woodall spa is a lovely posh place might be a bit pricey. It's actually quite far away from me so I can't help much more there.
Now Louth is the higher end of the East Coast and wolds. Lots of the lawyer's round here love there and travel in because of that. It's got a few shops and supermarket. It's a very beautiful village with areas like Huberts Hill to cost and about 30-40 mins from Skegness beach. The housing is pretty affordable but more than the East Coast which has far more poverty. There is a huge parking issue so whatever you do get a place with a driveway!
They have some great schools up there which is good including a Grammar. Erm, just don't go to Monks' Dyke. Yeah
St. Bernard's School caters for additional needs and learning disabilities. It's highly recommended although I have never been.
Horncastle is different entirely. The good parts are that it's on a direct route to Lincoln. Making further education and college choices easier. There are very limited further education facilities in the Skeg to Louth sort of area. Some schools don't even do 6th form! It is a wonderful place and has a big supermarket. Again it's about 45 mins to a beach. The people there can be a bit old and snooty! Itsgot far more young people though which sometimes seem a bit thin on the ground round here. Because it is on the bus route to Lincoln there is some antisocial behaviour at night in the centre which is only fair to mention. Usually drunks.
I think St Lawrence School is the special school in horncastle. They also have independent and Grammars within travel distance. Not sure about the academy schools. But they do have some. Check out Lincolnshire County Council website.
Finally it is worth noting we have some excellent Special schools in Spilsby. People come from all over the UK to place their children there. I think it's the Eresby School? Your going a bit more rual, harder to find local jobs, more travel I guess. But your not far from Boston. That being said there are nice posh areas in Spilsby and I hear good things about their Academy school. It's one of the better Academy down this end. I don't know what special needs your little one has but it's well worth taking a look round that school! Also the house prices are cheaper down this end so that's a bonus!
