I think it's been covered, but I agree, both of those are reference items, notes, not Next Actions.
When a birthday comes up, you can review your "Potential Gifts" list; or, if it's person-specific, you might keep an "Agenda" list with all the topics, actions and information you want fresh when you are going to meet that person.
Travel destinations aren't really actions, unless you trip in planned and you have specific actions, "Make reservations at ...", "Plan afternoon in ...", etc.
Travel is clearly reference material. I have hundreds of URLs, articles and lists in my "Destinations" notebook in Evernote, each tagged by Destination; and some with "Dining" or "Outdoors". I may never get to Reykjavik, but if I do, I'll review my "Iceland" notes before I go, and add specific actions to my MA lists.
