People tend to check in during these times:
These guys are COOL! They carry Luxury Pets items and currently the beds are specially priced about 50% off of our regular retail prices. Go into the SF hotel and get your bed.
Drop off before 10AM if you want them in "all day play", which you probably do. They're serious about the deadline!
Look out for groupons! Great deals :)
If you have a puppy, they offer day care w/o "all day play," which makes it great for them -- some interaction with other dogs plus some r&r through out the day.
