If you choose to spend your vacation at a 4-star hotel in Oakland, you'll typically find plenty of conveniences to make sure you're comfortable, such as a gym, restaurant and pool. You can experience top-quality service and upscale surroundings. Pick a 5-star hotel and you'll get a few more bells and whistles — think around-the-clock concierge, on-site spas and opulent turndown services. You're likely to get more amenities and premium services at a 5-star getaway, though both are fabulous options for luxury guests.
