While we've not taken a Tauck river cruise, we have taken 3 Tauck land tours and have just deposited for our 4th land tour for 2013. You could not go wrong choosing Tauck. They offer a stellar, upscale experience from start to finish. Several friends have taken Tauck river cruises and have given glowing reviews of their experiences. Tauck may appear to be more expensive, but when you factor in everything Tauck includes, as well as a truly upscale product, Tauck is clearly the winner when it comes to river cruises (and land tours).
