If you decide to vacation at a 4-star hotel in Oshkosh, you'll usually find lots of amenities to make sure you're relaxed, such as a pool, restaurant and gym. You can look forward to high-quality service and upmarket surroundings. Go for 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 extra amenities and first-rate services at a 5-star stay, but both are superb options for luxury guests.
