I made sure that all my puppies were very familiar with and comfortable with being crated before we took them to a hotel room. So there was never any noise when they were crated. I'm also a believer that tired puppies (and dogs) are good puppies, so we made sure they had plenty of time to walk and sniff outdoors, them played a nice game of fetch in the room. As Tux's mom said, we never left them in the room alone as puppies, even though they were quiet in their crates. We either ordered in, brought take-out back to the room, or went and ate take out sitting in the car with them.
Now, as adults, they will all (or alone or in any combination) stay quietly and happily in their crates while we eat elsewhere, but we don't leave them alone for long periods, even crated. If we DO leave them crated, we put the "do not disturb" tag on the room door, and leave our cell phone number with the desk in case of emergency.
It also helps that our dogs are indoor potty trained, and will use a UgoDog set up for them. This is a HUGE help first thing in the morning when you are on the 17th floor!!! If your puppy isn't 100% reliable in terms of potty training, I would keep a belly band or panties on them at all times in the hotel building. They do NOT like accidents! We also always bring bottled water for our dogs, as we have found that new water supplies sometimes cause upset tummies.
Finally, we bring sheets to put on the beds. Our dogs are used to snuggling with us, (even though they sleep in their crates over night) and even in hotels that don't have rules about dogs on the furniture, we think it's just polite to keep feet and hair off.
A friend of mine and I have traveled two days by car to the national specialty with as many as 5 Havanese, and we've made it work!
. We love having our dogs with us, so it was important to us that we teach them good "company manners" and introduce them to traveling often and early. They are all good travellers, and have been from Georgia to Prince Edward Island and from Cape Cod to Chicago!
