Wow I have a lot of options to choose from. Now everyone mentions acclimating... How serious is the thiner air? I know this is not Mt. Everest but honestly, is it that easy to get mountain sickness? Using myself as an example... I am 29 years old, in great physical shape, but I live at sea level. Do you think I am still extremely prone to feeling the effects of the thin air? Is sleeping at the Portal for 2 nights not enough to get my body adjusted? Should I be sleeping higher?
