Guitar Woes

So here's the deal, I acquired an old classical guitar from my neighbor a week before I went to camp. I did not take it to camp because I didn't think I had enough skills to practice with it, or the room in which to be able to take it home. At camp I practiced on my friend's guitar and I have gotten much better even in my Dad's eyes, but he does not support me taking it with me to Israel, where I will be spending the next year for college. I know that there will be others with guitars on the trip but having one of my own would be tremendously convenient. I would not have to ask others to borrow their guitars and I could play with them and not have to borrow from them. I believe that it's a good idea to bring the guitar with me. I know that a year off would hurt my skills and it'd be hard to catch up. On the flip side, I believe that having the guitar with me would enable to me to practice often and get a lot better especially when I come back after 9 months of being away from home. It would give me activity to do that doesn't involve a computer video game or things more detrimental to my brain power. I do have a hard case that I could check it in to the airport when I travel. Also it would be my responsibility and my hassle to deal with the extra charge for checking it, or if I carried it on I'd have to bring one less carry-on bag, which shouldn't matter to my Dad but it isn't. His direct quote was that he wouldn't forbid me from taking it, but he thinks it would be a very bad idea. I disagree with that...What do you think? I could use some inspiration.
