<u>A. She met her friends in the lobby of the hotel, and they headed over to the pool for a cool, refreshing swim.</u> This sentence is the best revision that tells all necessary details.
She met her friends at the hotel’s bottom floor, which is the lobby, so that they could head over to the swimming pool for a cool, brisk swim.
Explanation:
Hotel being a location, it is okay to use 's as possession instead of <em>"of"</em>. In this phrase, it is much clearer that the bottom floor is the floor in which the lobby is. Also, the phrase gets a better flow with the correctly placed commas.
Lots of people refer to cold as a personality like ruthless or mean so mint is just another way of saying something like her life was icy cold or she gave me the cold shoulder.
