If you choose to stay at a 4-star hotel in Cromwell, you'll usually find plenty of conveniences to keep you relaxed, such as a restaurant, pool and gym. You can look forward to high-quality service and deluxe accommodations. Pick a 5-star hotel and you'll get a few more perks — think around-the-clock concierge, on-site spas and indulgent turndown services. You'll most likely get more amenities and first-rate services at a 5-star stay, but both are awesome options for luxury travelers.
