Yes, they would. Staying at a resort does not dissolve the functions of your backpack. Even at a resort, backpacks are still useful, I mean, you will still go backcountry skiing and you’ll need to carry your gear. Whether sporting a small ski backpack to store your gloves, extra scarves and mobile phone to your snow car ride or carrying a large backpack to your long ice hiking activity, backpacks still are helpful at resorts.
