7. (They are both the same price, and go to the same places but the people working for grayline are much nicer and explain more what you get, I don't remember the exact price, but it's around 53-54$/per person)The lobby is quite large and very modern, lots of couches to sit, and a small bakery if you need to grab a muffin and coffee, it's a bit pricey but it's expected since it's inside the hotel.
