Not all pet friendly hotels and accommodations are created equal. Pet policies vary widely among pet friendly accommodations. Some hotels are only dog friendly; some pet friendly hotels only allow pets under 25 lbs., some have a 2 pet maximum, and almost all of them charge a pet fee - ranging from $10/night to a non-refundable pet deposit upwards of $100 (a.k.a. pet fee).
There are, however, some standout pet friendly hotel chains that allow your pets to stay for free. Trips with Pets lists Pet Friendly Hotel Chains, where you can look up your intended hotel and check their pet policy.
