In general we had a wonderful time with many thanks to our tour guide Renata. The sites we visited and the information that was shared with us by both REnata and the local guides was very much appreciated. A few minor issues. Though we had no difficulty with the walking aspects of the tour, a few of our fellow traveler who were "older" were not aware that there would be so much taxing walks up and down stairs and on cobbled streets. I suggest your brochure fore warn prospective travelers of this requirement. When we received final documentation we were advised that optional tours that we would sign up for with our tour guide would have to be paid in cash. I contacted the smartours office to express my concern for having to carry almost $1000 in cash in lieu of paying by credit card when we took your South Africa tour 3 years ago, I was informed that it the policy for the Eastern Europe tour to only accept cash. Lo and behold the first day of our actual tour Renata our guide informed us that we could sign up for optional tours and pay in cash or Credit Card. When I told her that we were advised we could only pay in cash she expressed surprise since Compass Travel for whom she works has always accepted credit cards for Smartours clients. You need to get your NYC team in sync with the folks who are actually conducting the tours for you. Many of the people on the tour shared our concern for having to carry cash when in fact your documentation advised us to be cautious of pick pockets!!!. I recommend that you change your policy and make it possible for travelers to use credit cards where ever.
