I drilled on ship, and was on the primary reserve crew. I was also active duty on a reserve ship. It didn't prepare me for the "fun" of last minute calls to show up on Friday, or not Friday but Saturday morning. Working uniform, dress uniform, civies. At the base, at the ship, at a bus, at the airport. And then the bus back to the base as you fall asleep and wake up an hour overdue because the driver didn't know which base or how to get there.
I was told not to do reserve on a ship, but I loved it, and wanted to keep up my sea duty time. Reservists at SIMA would show up fixed schedule, leave fixed times. And when a game was going on that would make traffic difficult, could show up early, and leave early. Skip lunch and skip out early to avoid the traffic.
Studying till 2300, falling asleep with your nose in a textbook, only to be shaken away at 0015 because the secondary crew has too many sailors who didn't get their sea legs, and a nor'easter off of Hatteras is too much for them. You have the watch.
I would do it again
You have the watch, it makes you stronger and builds character.
Besides, if you can get a JAG summer drill assignment, I would think that would be helpful.
Come on, would you rather have the watch or be sitting at home watching SNL. TV will always be there, but having the watch on the bridge during a nasty storm. You know you want to do it.
