Did exactly that, and it worked great! Thanks for the tip!
This area of the Gate42 AC turned out to be very quiet and definitely not crowded. Could leave doggie there with no problems (in her kennel) while taking a shower, and no one (I asked everyone around before letting her out later) objected. The lady at the front desk was unexpectedly sympathetic as well when she handed me my drink vouchers.
