I admit to only having tried the little Motorola's, but we found issues with the shape of ridges at large resorts. Pretty much you needed to be in the same vicinity. If the mountain intervened, no reception. You couldn't end up in different drainages. We did use those traveling across country in vehicles where they worked perfectly. My daughter used to take extend exception to their bulk as well (which to me wasn't much).
That being said, here you'd do better with radios than cellphones. Neither would be even close to 100%.
