I will be in Vegas for a conference early May. I belatedly decided to look into lodging at GC south rim. Only rooms available within the park are Maswik North section and El Tovar terrace. I read here that the El Tovar is a nice place to stay, but not the terrace rooms, so I went ahead and reserved the Maswik -- 3 nights, two adults, no children. Anyone recommend that I change?
