Part 2. Example
Although I did enjoy the food here, I was completely unimpressed (and slightly annoyed) by the overpriced margaritas. I ordered a platinum which contained "fresh" juice. It tasted like it had sprite in it, so I thought surely she gave me the wrong one. It turns out that "fresh juice" is really margarita mix on tap from the same gun as the sprite. I asked for something fresh to replace the horrible margarita and received a rocks glass with just muddled lime and a salted rim. I'm not sure it contained any tequila. Horrible! It's not that hard to make a fresh margarita!
Answer: 2 stars
Explanation: The writer has been annoyed in this place and has enjoyed the food. So, "2 stars" sounds reasonable for it.
Part 3. Exercise
Stayed here with some friends over Labor Day weekend for three nights. Overall, it was a nice hotel.

Pros:
Room service provided very delicious breakfast.
Lighting in the bathroom was AWESOME for doing make-up
Plenty of mirrors and closet space.
Comfortable beds.
Nice View.

Cons:
"Free" wi-fi is completely useless.
When we ordered room service (which we did several times) we'd call to have them pick up the trays outside, which they wouldn't do for several several hours.
Housekeepers tended to enter the room without knocking first.

I enjoyed my stay here very much, but having NO wireless internet, and virtually no reception at all, my phone became useless as soon as I entered the room.
Answer:
3 stars
