Pre visit locations really necessary?

A visit to Washington was scheduled in mid-June 2016, for a congress trip for a large Dermatologists congress in March 2016 in Washington, Els4Organising was taking over the organization. A pre-visit turned out to be a good move and certainly needed. Hotels, restaurants and transfer were tested. Staying in a different hotel every night and experiencing how you like it. What about the noise pollution of a hotel, how is breakfast served (plastic plates and cutlery?), how does the food taste in restaurants etc. Not an annoying assignment, but in case of bad experiences you also have to quickly find solutions again. You can arrange that on the spot. In addition, we have found special places. How about a dinner on the roof of a hotel next to the White House or a lunch in Restaurant Lincoln with a floor in pennies? Yes, a pre-visit is really necessary!
