After my first-ever group tour in Vietnam with G Adventures, I was curious how another tour company would compare. So this summer I booked Collette’s Majestic Cities of Central & Eastern Europe: Berlin, Prague, Vienna, Budapest and Krakow, with quick stops in Dresden, Bratislava and Slovakia’s Low Tatras along the way. Here’s what it’s like to travel with Collette: the group, the guides, the food, the pace and who I think it’s best for. Berlin Wall and memorial, Gedenkstätte
