Swim Cap questions..help?

Hi I'm on swim team and we all wear swim caps for practice and meets. I'm letting my hair grow out longer but it isn't long enough to pull back into a ponytail or anything, so what I was wondering is if anyone has suggestions on how to keep hair from looking like a complete disaster and spiking up after I take my cap off? Does anyone use those rubber band type things(they are like giant rubber bands and come in different colors) thanks
