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
Not everyone can be a King or Queen, but at least at Excalibur guests can stay inside an enormous castle-- for cheap!

At over 20 years of age (opened in June of 1990), this hotel is now one of the older ones on The Strip. The decor and furnishings in my guest room were kind of dated, but the room was clean and comfortable enough-- and had a view of New York New York and it's rollercoaster across the street. Check in and check out were a breeze, and a $20 credit for food and/or drinks at several hotel bars (plus a whole bunch of other coupons) was included. The room rate for the night I was there was only about $30, but even after the $20 Las Vegas 'resort fee' was added I felt it was still a good deal.

This property is IMMENSE; I found myself getting lost here repeatedly. Of course, I'm sure that's intentional since nearly every path leads back through the casino floor or past shops and restaurants en route to another casino floor. Once inside, it's a bit of a challenge to escape to the outside world again!

I was a little disappointed to find that Excalibur's "Fun Dungeon" is NOT, in fact, an S&M-themed brothel, but rather an arcade and midway. Oh well...
Answer:
4 stars
