In reply to thegrowler1981:
I would view a single skin tent as a beefed up bivi - it gives you a bit more protection, can be warmer, and as long as you haven't had a catastrophic fall out with your partner better morale in a shared space if it isn't all going quite to plan.
For your described purpose it sounds like what you want; the advantage of a single skin (space and weight saving) over a free standing two skin tent (more comfortable for multiple nights) is considerable.
What Tom said about huts is worth thinking on, but the €400 cost of a tent won't buy you and a partner many hut nights, and in certain circumstances being closer to an intended route (because you are in a tent closer than the closest hut) can be helpful.
And it obviously gives more versatility.
(Having said this, there are obviously times when a hut will win out hands down - the walking in through the rain because the weather tomorrow will be stella situations for example.)
