Explanation:
In this question, we need to choose the correct article to fill in the blank. Let's understand the different options and their usage to determine the correct answer.

a: The article "a" is used before words that begin with a consonant sound. For example, "a dog," "a cat," etc. However, in this question, the word "hotel" begins with a vowel sound, so "a" is not the correct choice.

an: The article "an" is used before words that begin with a vowel sound. For example, "an apple," "an elephant," etc. In this question, the word "hotel" begins with a consonant sound ("h"), so "an" is not the correct choice.

the: The article "the" is used before specific nouns or when we are referring to something that has already been mentioned. For example, "the dog that I saw yesterday," "the book that I am reading," etc. In this question, there is no specific hotel mentioned, and we are not referring to any particular hotel, so "the" is not the correct choice.

a: The article "a" is used before singular, countable nouns when we are referring to any one of a group. For example, "a book," "a pen," etc. In this question, we are referring to a hotel in general, not any specific hotel. Therefore, the correct answer is "a hotel."

Summary:
Based on the rules of article usage, the correct answer to fill in the blank is "a" because we are referring to a hotel in general, not any specific hotel.
