If you get a 4 year NROTC scholarship, you will be going on navy "cruises" during your summers, they are pretty badass so don't feel bad about missing out on summer.
First summer - CONTRAMID, basically you go all over the place spending time in the various navy communities, Surface, Subs, Marines, Aviation(some even get some stick time)
Second Summer - You function as an enlisted sailor on either a surface ship or submarine.
Third Summer - By this time you will need to have pretty much made up your mind on what community you are interested in, and you can be in a junior officer slot on a surface ship, sub, or aviation squadron.
