if you want a hotel with lots of activities, your best bet would be a deluxe resort But it really just depends on what things the teen (and really the whole family) is interested in.
it really depends on the teen. my family stayed at Pop Century and i loved it, just walking around and observing was good enough for me. then we moved over to AKL halfway through (most amazing surprise ever) and it was so amazing. we dont normally spend much time at our resort so a pool and gift shop keep me busy enough ßÍ
