I was wondering if I could get some reviews on this Riverboat cruise during summer travel. We are considering the Smartours MS Kronstad St. Pete to Moscow trip this July or August but have never been on any kind of cruise. I'm concerned about AIR CONDITIONING in the cabins mostly (I have a major problem with getting sick in hot weather) , the food, pace of the trip, and any general comments on river cruising in general. Do you feel really cooped up all the time, is it noisy all the time on the ship and do you feel that you get to spend enough time at each port to get a feel for the place? Any comments would be most appreciated. Thank you!
