I have a dog but was on a business trip so did not have to worry about hotel being pet friendly. Typically, the Marriott properties that are pet-friendly are Residence Inns and TownPlace Suites. So I would recommend checking for those places in the area.
Actually, I just checked the hotel website. Pets are not allowed.
I didn't see any pets, that I recall but most Courtyards are. I would definitely call them.
I agree with the reviewer above. I was there with my grandson scouting him attending Baylor. I don't have a pet, but I have a teenager.....
As a guest to the Courtyard Waco, I did not have a pet so I can't help you with your question. If you don't see it on the website, I would call them. They have a very friendly staff that will be happy to answer your question.
