If you decide to spend your vacation at a 4-star hotel in Amazonia, you'll typically find plenty of conveniences to keep you relaxed, such as a restaurant, pool and gym. You can look forward to top-quality service and upmarket surroundings. Pick a 5-star hotel and you'll have access to a few more perks — think on-site spas, around-the-clock concierge and indulgent turndown services. You'll most likely get more amenities and exclusive services at a 5-star retreat, though both are great options for luxury travelers.
