If you decide to spend your vacation at a 4-star hotel in Shannon, you'll usually find plenty of conveniences to keep you relaxed, such as a gym, restaurant and pool. You can look forward to excellent service and upmarket accommodations. Opt for a 5-star hotel and you'll get a few more bells and whistles — think concierge assistance, on-site spas and indulgent turndown services. You're likely to get extra amenities and first-rate services at a 5-star getaway, though both are fabulous options for luxury guests.
