Going to Mount Rushmore area with 2 dogs, doggy day care?

We bought a Temperature Stick and have tested it with the MiFi Jetpack. So far, so good.

On our journeys we are usually gone for just a few hours. Next summer we are considering a more ambitious trip that will require us to be away for longer periods during the day.

If we're staying at a state park or COE park I don't think we'll be able to use a local sitter. Has anyone used a service like rover.com?

Our guys are pretty laid back, they get excited when they hear the key in the door.
