My wife and I will be in Colonia the nights of January 30th and 31st. From what I have heard, there may not be enough to do in Colonia to warrant a two night stay, but we already made our plans, and paid for the hotel. Could someone reccomend a good day trp from Colonia? We won't have a car, but could take public transportation. Also, will there at least be restaruants open New Years Eve? Any help would be greatly appreciated.
