so…after lounging at the pool for a few hours today, i went back to my room and my key had decided to stop working.   i then had the amusing task of going to the front desk in my pool lounging attire!!!  they  told me my key had been demagnetized, how i am not sure since all i took with me was a bottle of water, a paperback and my key!  it must be my highly magnetic personality, muahahahaha!!
