Have a good trip. Since its on the subject of what to do when boarding, I'll give my late advice for other people.

Try not to bring your own kennel unless they specifically request it. Also, let them provide the blankets if they have blankets for every dog. Speaking from experience, dogs who are being boarded and become a little scared sometimes hole up in their own kennels or beds within their enclosure and become protective and dangerous. I've had to use a catch pole to get a dog out of her little pink kennel once and then had to remove the kennel from her enclosure. The owner was not happy with us, but how were we supposed to walk the dog who was growling and biting and wouldn't come out of her kennel? Once it was gone, her protectiveness went away.
