Hi Dan
I have only done one RS tour, it was the 14 day Family Europe tour, and it was great. It is not a cheap tour, but , the value is definately there, I felt I had to spend very little extra,, just half my dinners,, and some lunches,, but lunches are often just grab and go sandwiches etc,.. I do not recall paying any extra really for sightseeing,, except the gondola ride in Venice.. which is optional( but everyone took!) They also threw in a few things I was not expecting,, drinks on the gondola, champane on the Pont Des Arts in Paris, a visit to the "Ice Man " museum on the Tirol mountains,,
I wish I could give you an exact number,, but really alot is left up to you,, how you will choose to spend your spare time,, some people on our tour chose to go hangliding in the Alps.. that was not cheap.. but my dd and did a hike and bought sandwiches that day,, which was cheap!
Figure 6-15 euros each for lunch,, less for sandwiches, more for sit down meal.. and about 10-20 for dinners,, wine could be more if you are lavish, or could be cheap... I find 50 euros a day covers me for ALL ( even breakfast) my meals in a day when I am NOT on a tour,, so on tour I definately did cheaper..
