tyres for alps.

Sorry for probably asking a question that has been asked many times before but could use a bit of guidance.
I'm running a specialized butcher up front and a specialized purgatory grid on the rear of my bike on easton haven carbon rims setup tubeless. I am perfectly happy with them and they havent been on long.
I'm off to Morzine in mid August for a weeks riding
. Having never ridden in the Alps before I have no idea if these tyres will be up to the job (durability / puncture protection wise). Do I really need to go up to dual ply tyres???
I was hoping to buy a spare of what I have on so if I tear a tyre I have one ready to go on and will be used to the level of grip they offer.

So my bike is a yeti sb66 and i am taking a set of 150 fox 34s and 160 fox 36s (will probably run the 36s im guessing) and my rims are easton haven carbon.
The tyres i have ordered are continental trail kings b/c apex protection 2.4.
As this holiday is a real treat for me I'm going to get some top end 3c tr exo maxxis!
Just need to choose between running a Minion DHF up front or a HR2
and weather it be a Minion DHR 2 or HR2 on the rear
I dont really want to lug a spare tyre out there if I dont need to, so will I be able to pick up a top end maxxis 26" in resort still? (if I ruin one on the trail)
