Absolutely. My daughters did this, for the first time, on our last trip (16 and 13). We had reached a point where, in order to continue enjoying our vacation, we NEEDED to split up... lol. My youngest, inspired by my doing all 4 parks in one day on a solo trip, actually did that! We were all solo for about half of the day and my girls met up by dusk (that was my only caveat, once it was dark, I wanted them together) - then met back up wth me at MK for us to all return to AKL together. They LOVED it! They kept in contact via their cell phones and I didn't worry a bit. Having been to Disney many times, they are very comfortable navigating transportation and the parks. I think it was actually a good experience for them!
