San Sebastian is VERY interesting. It’s a spectacular field but can be very demanding when the wind is blowing, due to combined mountain and sea effect. I’ve always found it to be a very friendly place with staff who go out of their way to be helpful.
Don’t forget that you can legally fly VFR on airways in France and Spain. Well worth considering from a range/time point of view. Also, this way you’ll get to fly OVER the Pyrenees <img src="eek.gif" border="0">
