**Key Considerations for Choosing:**

* **Purpose:** What kind of posts are you tagging with this? Are they reviews? Promotional material? Itineraries?
* **Keyword Density:** Make sure the description naturally includes relevant keywords to help with search engine optimization (SEO).
* **Brevity:** While you have room for a decent description, keep it concise and to the point. WordPress tag descriptions do not have to be large.
* **Target Audience:** Consider who your WordPress audience is and what information will be most appealing to them. I’ve aimed for language that is both informative and slightly attractive for prospective customers and readers.

I recommend picking the option that *best* fits the tone and subject matter of your blog and of the posts you write *about* the cruise line.
