Explanation
Reach and frequency buying can give you more predictability and control over the following:
* Reach and CPM
* Frequency
* Spend per day
* Placement distribution (e.g., Instagram vs. Facebook)
Keep in mind that you need an audience of at least 200,000 people in order to use the reach and frequency option. Additionally, you can only use reach and frequency on saved audiences and in multiple placements, not just Facebook Feeds.

Explanation
You need at least 100 events or users who have made a specific action on your website for you to be able to build a similar audience.
In this case, you still don't have enough events or users who have purchased on your website (72); so you are left with two options:
* Build similar audiences based on people who have visited the main landing page of the product.
* Build similar audiences based on people who have made specific actions events on your website: Add To Cart and Initiate Checkout as they both have more than 100 registered actions.
You don't necessarily want to start building an audience from all website visitors as this might be too broad.
You want to build your audiences first based on the bottom of the funnel and then move up.

Explanation
The best solution is to create a Global Brand Page and then create multiple locations:

With Locations, businesses can:
* Help customers find a business faster
* Offer localized content
* Manage all locations in one place
* Aggregate check-ins on the Main Page
* Manage local Facebook ads

Explanation
Keep in mind that the client wants to encourage people to finalize booking on their site. So you are looking at conversion or bottom of the funnel ads.
In this case, you need to launch conversion and dynamic ads in order to get the most results and optimize campaigns based on specific results on the website.
Be careful in these type of questions, look for phrases like "people who've visited the website" and "complete a new transaction." Traffic ads would be valid for new traffic generation; however, this client wants to focus specifically on conversions. You also want to use dynamic ads since your client has multiple locations so that you can optimize ads by location with their audience.
