Talk to hotel directly
It's a good idea to personally and directly contact the hotel, for a number of practical reasons as for instance:
1) Double checking the lowest rates and discounts offered by resalers and reservation agents. Hotel reception based on occupancy may offer lower prices and other benefits as a free room upgrade.
2) Getting information about the hotel, its services and the area. You could ask if your personal requirements are all met by the hotel services and, if you are a first time visitor, get local advice for restaurants, transports, directions, weather.
