I have bought macarons from Kayla's Cakes before and brought them home. I bought them in my carry on bag instead of packing them in my suitcase. At Kayla's Cakes they are individually wrapped and the box is very sturdy so they don't get crushed. The little stand keeps them in the refrigerator but they don't have to stay refrigerated after you buy them. I did keep them in the fridge in my hotel room though until I checked out.
If you buy macarons from the Jolly Holiday I would suggest as a previous poster said buying them before you go and bring some ziplock bags with you to put them in so they stay fresher. And something sturdy to put them in, perhaps you have a plastic container you could keep in your carry on bag to put them in so they don't get crushed.
Personally I really love the macarons from Kaylas Cakes, they are the closest I've ever had to matching the taste of the ones I had in Paris at Laduree.
