When we arrived in Vienna, it was very confusing because there was a man with a Tauck sign at the airport, but he was not expecting us. Fortunately, my friend spotted another man carrying a sign with our names on it - even though we were told to look for a Tauck sign.
Tours were too early in the day - even when they didn't need to be to fit the overall trip. No good alternative if you were not able to walk a long distance and climb a lot of stairs or inclines. No activities on the ship if you chose not to participate in a tour. Also, information on the trip was not given far enough in advance and we would only learn about the next day's details the night before. Basically, Tauck's attitude toward their guests is - 'HURRY UP AND WAIT'.
Way too much time on buses. Tours were disorganized and there was no 'plan B' if the weather turned bad or if there was another problem. My group was forced to stand in the rain for over a half hour at Cesky Krumlov in Czech Republic and when we asked if we could proceed to the lunch location to get inside we were told NO by the Tauck director because we couldn't arrive before the scheduled time and we were told to go to a coffee shop to wait.
