Ok! First thanks for the prompt replies.

 Westy is back in the driveway drying out as we speak.  We went back for
her about two hours after we left her, added the last of the coolant I
had to the expansion tank and then filled the coolant bottle with water
and added that weak mix till topped off.  I then started her up and
topped off some more as needed.  Total took about quarter gallon pure
and half gallon weak mix.  Ran fine on the way home temp gauge at normal
and no blinking light.

 I have now removed the pergo wood floor, carpet underlayment and the
heater core.  Also found lots of interesting trash and some coinage!
Everything has now been washed with water and its all opened up to dry out.

 So is it better to join the two hoses or cap them? Also should I just
try and measure the concentration and add water/coolant as neeed or
flush all over again?  Thanks again for all the help.
