On my first thought, the only two negatives about this trip is; first, minimum of 4 pax required. Second, in the case of insufficient participant, they might arrange non-English speaking tour guide which might be troublesome for foreigners.
Good thing, we manage to see what we yearned for, even sea of clouds were there during sunrise. It was all worth it. Not to mention, you are in good hands with the awesome tour guide, Ji Ge (吉哥). His skilled manoeuvre through the hilly roads under low visibility is commendable.
