1. Calais is class D and the cat A aircraft price is only a few Euros more,
2. Yes, in my experience it is less prone,
3. Yes, although a taxi is not hugely expensive and readily avialable, usually the same gentlemen who often brings his wife with him,
4. I had heard the resteraunt had very recently re-opened, good news indeed,
5. Never known French only all the times I have visited,
6. Yes, but strictly you need to give advanced notice for Customs (it is PNR) and you will get a good dinner in town if you are prepared to take a taxi,
7. No, Calais is great. I was a freqquent visitor to Eastenders for fairly priced wine before the Euro became less attractive and while of no interest to you it is a super place to fly a few approaches for diddly all. L2K on the other hand offers a very pleasant walk into town, the towns and beach are great, as are the resteraunts, you can walk or hire a bike and the place has an elegance that makes it attractive. Thats why people keep on returning. IMHO they have got it spot on. Calais on the other hand just has a lot less to offer.
