Is it a full uplift holiday you're going for? If so, I advise you buy a used DH bike for the trip, and sell it on again once you get home.
I did the Alps with my trek remedy this year and it was horrible. Braking bumps and really rocky compressions and berms toss a shorter travel bike around a lot more, to the point where I simply didn't enjoy the riding aspect of things (plus the shocks didn't seem very plush either but the bike's gone now thankfully).
You can get a good useable DH bike for 800 quid if you take your time choosing. Then even if you lose £100 of that when you sell it back on (and I reckon you'd probably want to keep it anyway) that's not bad to give you a real feel for what the trails over there are like.
