Probably a weekend hiking in Luxembourg in the spring and a week hiking in the Pyrennees in the autumn. My wife and I haven't made any arrangements for our main holiday yet, but we're thinking of spending a few weeks driving round the south of Spain. After last year (a week in Las Vegas, half a week in Luxembourg, a fortnight in Curacao and Colombia, several trips to Scotland, and a fortnight in the Caribbean and Miami) we'll take it a bit easier this time round.
