The Hampton Inn Vallejo sits right off Interstate 80 near the Fairgrounds Drive exit, which means you’re close enough to grab coffee and hit the road, but also positioned for exploring Mare Island and the waterfront without fighting downtown traffic. The hotel has the standard Hampton setup—clean rooms, a small pool, and a breakfast included with your stay—but the real draw for traveling with dogs is that they genuinely allow them without the usual corporate hand-wringing about damage fees or weight restrictions.

Dogs stay free at this location, though you’ll want to confirm current policies when booking since Hampton’s pet rules can vary by property. The hotel assigns designated pet rooms, so request one when you reserve rather than showing up with your dog and hoping. Most rooms are standard doubles or queens; some have either a microwave and fridge or a full kitchenette, which matters if you’re planning to prep meals rather than eat out every night. The rooms are modest but functional—nothing fancy, but they’re reliable and the beds are comfortable after a long drive.

The immediate neighborhood around Fairgrounds Drive is industrial and commercial, so you won’t find a dog park next door. However, Vallejo’s waterfront parks are about fifteen minutes away, and Mare Island has several walking routes and quieter beach access that dogs enjoy. The hotel sits near Highway 37, so driving a few miles gets you to more interesting terrain than the parking lot area. Breakfast is served in the lobby each morning and includes the standard muffins, waffles, and cereal—nothing gourmet, but it saves you a stop. Rooms run around $100–140 per night depending on season, and if you’re passing through on I-80 with a dog, this is a straightforward, no-surprises option that won’t charge you extra for traveling with your dog.
