I have seen all kinds of pets. Especially in RI. Williamsburg, Va to Scottsdale, AZ. You need to register your pet, and sometimes pay a fee. But realistically, it may be a lot cheaper than using a kennel.
I love pets, but I am concerned that it could get out of control. Many people are allergic to animals and it could become just too much. I hope not, but?
Call the hotel directly and see what there policy is. Good luck!
When you are on the Marriott.com homepage (hotel page) click on the 'advanced search' feature at the bottom right of the "FIND__Hotel __Deal__Meeting Space" box. On the next page (that you are sent to) in the bottom center there will be a "Other Ways to Find Hotels" box. In that box there is a "Pet Friendly" feature. When you click on it all the pet friendly Marriott hotels will come up and you can search any one you are interested in.
Hope this helps.
