I know that ABD does not do river cruises but I am having trouble finding real feedback. I am looking to take my parents and my 14 year old daughter on a river cruise to eastern Europe. It looks like Uniworld, Tauck and Viking all cruise there. Anyone have an idea where I can find reviews, information regarding the ships and the included tours. How do the manage the daily tours, what size groups ... Thank you!
I wish ABD would have some river cruises! I haven't taken one yet, but, if allowed here, I will share what I have learned while planning our upcoming Sept river cruise on the Danube, from Budapest, through Central and Eastern Europe to Bucharest and ending in Istanbul, Turkey.
I started by going to Cruise Critic, there is a forum board there called "river cruising"; I started by reading as many "which line should I take" type threads. This helped me winnow a cruise that work for our travel party (just me and my DH, youngish, very active 50s with no kids traveling) Based on that I chose AMA, as their average age skews 50 ish and they offer many more "active" amenities that appealed to us. If you are traveling with a teen and grandparents, you might want to look at a line like AMA or Tauck that specializes in a mix of active and "gentle walker" excursions. Their aren't a lot in the way of "kids" activities on the standard lines, but if you choose an itinerary that has ports every day with little day time cruising, you can select excursions that will appeal to your family group and to your 14 yo.
After getting an idea of the best line for your family, move on to ABD trip reports, Trip Advisor and the Cruise Critic River Cruising port boards to search the cities and towns on the itinerary of your chosen line. These will help you discover what to do in each port. The ABD reports with "pre nights" reviewed will help you find guides and sample itineraries for the major Central tend Eastern European capitals. These sites are especially useful in getting good advice and reviews for private guides in the cities. This will likely be cheaper for 5 of you than taking ships excursions and you can tailor your touring to the mixed interests of your group.
I also invested in Rick Steeves books for the specific cities in my itinerary; Budapest, Istanbul. These were highly recommended to my by people who have been and my TA, for that part of the world. I also got the DK guide books for those cities. We love DK for its photos and trip useable " attraction" maps, especially in countries were the language is so different, and the guide books or maps at the attraction may not be in well translated English. Also, when traveling with a group, DK, is a great "flip through" book, where family members can look through quickly, and if a photo of an attraction or activity appeals, stick a little post it on it, and then you can sketch a rough tour itinerary from that. The multitude of pictures make sit it easier to show your group what's there vs everyone reading a 300 page book!
I made a spreadsheet with the approx prices and amenities offered by each line, but in the end, we chose based on what seemed like the right match, and that required a lot of reading reviews both by travelers and by editors of travel websites!
On last thing- Wendy Perrin of Conde Naste Traveler did a very nice review of several lines...

Now, my own opinion, is that she was very biased towards, going inexpensively and touring on her own, so she didn't take into account the same concerns you might have traveling with 3 generations and wanting some more options than she needed. She also obviously didn't get to preview every line and was mostly on a given lines "newest ships" (since that's what's being "promoted" by the lines) , but it's a great starting point to get a "feel" for the various lines.
Best of luck! If you are planning for further out than Oct 2014 ( and I hope so, cabins on river cruises fill fast, and less than 6 months might be tough to find 2-3 cabins on the itinerary and dates you want) I will be doing a full review under this same screen name late next fall. It won't be on the ABD Boards, but you can find it by googling!
I'm hoping what I've shared is helpful and not so off the topic that I've offended the mods here

Maybe one day soon, there will be an ABD river cruise to review!
