Is your battery running out at the Park? We recommend this charger, it charge your phone 6-8 times (full charges), it is amazing http://amzn.to/vEV5VF (MW benefits if you purchase)
Would anyone here be interested in a Disney Book swap? I'd organize it if enough were interested. The books you offer would be borrowed by others. Please note you would have to pay to ship books you received and I would have to not be held accountable if someone didn't get your book back to you (which I doubt would happen).
