Perhaps you can convince your family, relatives and or friends to do some road trips or "education vacations" as my dd calls them. I'm not sure where you live, but a family trip or two to Washington DC and the Naval Academy may help to fuel your goals and dreams. My dd just returned from a weekend (CVW) visit to the Naval Academy and loved it, especially just walking around the campus checking out the buildings, attending classes and even going to a rock concert.
However, if your family is more interested in having you stand in 2 hour lines at Disney World for 2 minute rides, then you should probably make a suggestion that what you really want for your birthday, holiday and whatever gifts should be directed to future Naval Academy opportunities, such as summer STEM & Sports programs, Naval hockey games and road trips. Disney is okay, but if money is limited, choose well where the $$ are spent.
Also, if you are planning to apply for ROTC as part of your Plan B program, you will need to select at least five or more colleges. Anytime we were on a road trip, we made an effort to visit the campus of a big name college just for fun and usually had lunch or dinner at the student center. If you are visiting the East Coast, the Coast Guard, Merchant Marine and West Point Academies are great destinations. It's a fun way to learn history too.
And one more idea... if you can attend a college graduation, that's also a good time to check out a college. Of course, attending a Naval Academy graduation would certainly be a plus if you can figure out how to get invited.
Hope this helps!
