We are a split family on deciding whether to add on Turkey or Adriatica to our Europe in 21 days tour next Spring. Has anyone done these combinations?
You are saying you are taking a RS Europe in 21 Days tour and asking if to add to that a RS Turkey tour or a RS Adriatic Tour?
I am not a huge fan of Split or Plitvice so I would have to go with Turkey, but only if you can spend at least 2 days in Istanbul pre-tour or post-tour (maybe post tour is better so you can avoid the RS tour places).
I would lean towards Turkey, but point out that most visits there miss out on most of what should be experienced. Yes, Istanbul is a good checklist visit, but there is so much more to Turkey than just that very crowded city. I always recommend that if you think you can give three days to Istanbul, then figure out how to visit Turkey for at least a week. Istanbul will not leave you with enough of an appreciation of the country, only strong impression of the city.
If you are invited for a coffee, be sure that your answer is yes.

If this is indeed what you're doing, you will need to have stored a lot of energy to add on another 13-14 day tour. I've not been on the Adriatic tour but I have been on the Turkey tour and can't imagine doing it after the 21 BOE tour - both tours have lots of bus time and are very active. As noted, the Turkey tour short changes Istanbul so if you choose that make sure you have at least a day or two extra before the tour starts.
It's probably unlikely many people have done the combination of tours, so as for how to decide maybe just draw straws, and save the other tour for another time.
A lot depends on energy level as described above. To me, Turkey is a place that some might feel more comfortable having a tour for (and for political reasons I would say go for it in case the country gets more difficult to visit in coming years--it is amazing!). Croatia is a place that is exceedingly easy to travel in, so it would be easier for me to put it off and visit anytime, with a tour or not.
I agree that you should go to Turkey when you can. I think the situation in Turkey could deteriorate in the future.
