The ads of FB are much more random spots, haven't really looked into this, but you are able to target certain regions or areas (I guess)?
You can target the ads on FB very specifically in terms of the demographic of the viewer - age, gender, location, marital status, interests, etc. The usual example of this is an ad for wedding services can be targeted to women between 25 and 35 in a specific city whose status is engaged.
You are right, though, that they might not be looking to book a vacation right now, since FB is not a search engine. For our potential guests, you could target a geographic region and then hope that they become a fan and will book with you when they are looking for a vacation because they follow you on FB. But an immediate booking is probably not as likely with a FB 'like' as it is with a google search.
