I have a 14 yr old and 3 dogs. In March when I was gone, I paid the high school senior we know well $400 from Sunday afternoon through Tuesday morning just getting daughter to school. Basically she was with my daughter from 1ish on Sunday, got her to school on time, met back with her around 6pm on Monday, got her to school on Tuesday am.
As for the pet care.....I had Debi with All Critter (here on Mamasource) double checking on the dogs. Debi is great by the way and we have used her services at least 2 other times as well. We'll certianly call her back.
Enjoy your trip!!
