this is my first year going, but i've heard about all about the dehydration issues. i've heard these tablets are good for keeping you hydrated, and they can easily fit in whatever bag you're planning on bringing along with you. spend money on staying healthy! http://www.amazon.com/Nuun-Active-Hydration--Electrolyte-Enhanced/dp/B005GQ6IN6/ref=sr_1_3?ie=UTF8&qid=1396026838&sr=8-3&keywords=nuun+electrolyte+tablets
Trying these out this year, should be a little more convenient than all the pedialyte bottles.
